Assignment

Use the images provided in the downloads to draw the Robo Bean and Anato Bean. Then add the oblique with the correct stretching, pinching, or twisting. Think about the motion and how the motion deforms the shape of the muscle.

According to the digital model, the origin of the obliques inserts just in the third/half of the lateral plane of the rib cage, approximately towards the middle of the height of the rib cage (at the fifth rib), above the level of the xiphoid process. It seems to me that in some of your drawings your obliques start out too low. But the gesture is very organic!

Hi, this is my oblique assignments. I did this first before watching the video, It seems for some reasons i Did not draw the connection to the serrator properly on the later drawing. Any feedbacks or critiques will be greatly appreciated.

My drawing of the model at 2:03. It was just so clear that I needed to capture it. Didn’t pay attention to the gesture at all tho but understood the insertions much better than before so that’s good. Ok back to the video :)

Hi everyone! These are my drawings for this lesson's assignment .Personally i struggled a lot with proportions especially when drawing the abs so maybe i'll practice them until i feel confident while continuing the course. Other than that, i also struggled with insertions but i got them figured out while making the skelly draw-overs. Anyway , i would really appreciate any kind of advice /critique.

I like them! Remember that the fiber bundles of the obliques are 8 in total, and they are inserted in a saw shape from the fifth to the twelfth rib, descending parallel with an inclination of 45 degrees and then widening as they are inserted into the semilunar line of ABS. . Some of the oblique fiber bundles you drew look too straight (they actually curve to the shape of the ribcage), too wide, or the wrong amount.

I did a few extra studies of the obliques over the weekend from some sculptures in my local art gallery in Birmingham (UK). The obliques were not always clear or obvious, but I had a go at putting them in anyway. For the last one on the right (the twisted back angle), have I got the obliques curving too far into the middle of the lower back? Gonna try another one of these for my more detailed, toned torso study.

This is the first part of the obliques exercise, I've still to pick my model references and work from those (which I'm looking forward to). I think I tend to make the upper torso area (ribcage) too long, and sometimes, too wide. All good fun though.

Nice! I think you get most things right. But there is some ambiguity in your drawings. Try to draw the whole muscle, all the way from where it originates to where it inserts. You're leaving white spots here and there making it feel undefined. It could be an artistic choise, but in anatomy studies when your goal is to understand the muscles, it could be useful to define the entire muscle clearly. When I studied the obliques, I drew all eight muscle bundles, and studied where they started on the ribcage, and where they inserted, tracking their path. Now that I have some more experience, I realize that that might have been an unnecessary amount of knowledge in relationship to my drawing skills, so take the advice with a grain of salt. However, I can't help but feel that it was worth it. I really understand the obliques now. Your drawings seem to lack some understanding of the path of the bundles and their attachments. One thing that helped me when learning the origin points, was to identify the line that would run through them. Highly recommend to give some extra time to studying the oblique in the back. It helped me with drawing the lower back muscles. You might find it useful to study individual ribs. Especially the 12th. When looking at the 3D Model: Male Rib Cage, the 12 ribs seem to attatch to the spine halfway between the sternum and the bottom of the ribcage. Hope this helps :)

Hi @Dylan Doster, nice work. These are looking pretty good. - I would study the attachments more. They feel a bit incosistent, as if the muscles were hanging loosely. Decide on exact points and try to hit those same points in every angle. In the 2nd drawing from the left in the bottom row for example, the abs originate too much to the left on the front plane of the ribcage. Before drawing the muscles, find the centerline of the rib cage and make sure the muscles attach correctly in relationship to it. One thing that helped me with the external oblique's origin was to imagine a line running through all the origin points and study were it is. - Try to make a more clean presentation of the work. If you're doing it digitally, save the work as an image and post that. It's good practice for presenting your work as a proffesional, plus makes it easier to critique. Hope this helps :) Keep up the good work!

I thought I understood, but when I drew it, I realized that there were parts I didn't understand. In that respect, the task seems to be important. 1. How many strands of the external oblique muscle should be used? How it transforms depending on the situation. The back is subtle. 2. I'm also not sure how the external oblique compresses when flexed.

I think that perhaps you should draw from real life references to help you see it better. I used to draw only from imagination until I realized every artist I love and respect uses reference religiously in their day to day work. 1. The number of strands isn't important. You will usually never see this under your fat. The most fit people may have 2-3 showing, if you really look for them. But, you may also be confusing these with the finger like muscles of the serratus anterior which weaves into the rib cage giving that shoe string look. On a well developed person this is much more visible with maybe 3-4 serratus muscles. For skinny people, it's too flat to see. In any case, for this exercise it's not important and if you were to draw a comic hero, why not give him 20 interlocking muscles, who's counting? Instead of drawing lines for the strands, you could just use a color and lower the opacity on the layer since you're using digital tools. 2. It generally pinches when leaning to a side that is active and stretches on the opposite side.

the studies are both about the ABS and the Obliques, so I'll post it on both

Nice drawings, good to see you do practice the gesture first. Just two things: Try doing more cleaner drawings. Your drawings are a bit scratchy. Also try spliting lite and shadow a bit more clearly. I would suggest you copy more of stans drawings. Your going on the right path. Good luck

Gosh. I thought I knew how to draw a box. There are two sets of drawings here. The first are my own attempt. I made a weak attempt to suggest the lower part of the obliques but, even after looking at the video again and looking at the 3D models, I couldn't visualize the upper part of the obliques (the part coming off of the ribcage.) So - yes, I gave up on that and just did another set copying Prof P.

Some more! I am very bad at this right now, I will study the 3D model and follow the examples to get the hang of it

Tried obliques assignment. Found it quite hard to predict the twist and bend. This almost made me want to give up on anatomy lol. I could use some help on how to draw them

There is no need to give up! I took a sponge an draw some lines on the surface. Therefore I could squeeze it and bend in all directions. After that I went further with the course. Now I go forward and sometimes back to give it a try again. That is my way and it is still working for me. Find your way, don't give up. Suddenly you will be able to solve your problems and that is the reward!
