these are nice :)

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.

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 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.

Nice job.

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

Doing it again, as I seem to have trouble with all the strips

Excellent!
