Assignment

I've posted 6 close-up images of Skelly's joints in the downloads tab. Your second assignment is to draw them as simple versions. When you try to put them into perspective, you may find it difficult, but I will have Marshall help you understand how to do it. Post your drawings in the Discussions.

Good practice on form. Looking forward to moving on and learning the specifics. Disregard the Skeleton head one,I will redo once I have more form and positional practice with the arms. Thought of a drill to do all rotation locations of the arm with simple forms. Need to do a cylinder isolation study to do that first.

These look nice! I like the inventiveness with the mass conceptions. I'll try to look for things to improve on: - I think you could improve the accuracy of your geometric forms (boxes, cylinders & spheres). The forms feel three dimensional, but are a little off here and there (shape, angle of ellipses, convergence). This is especially clear in the spheres. If you want to work on this, draw 3 boxes in different angles from imagination, and do the same with the cylinders and boxes. Then tag me (@Jesper Axelsson) if you want me to take a look. When you draw: Draw through (drawing even the non-visible parts (lightly), as if the object was made out of glass). Boxes - Make them cubes (all the edges are the same length in space) Try to get the convergence right Cylinders - Try to get the convergence right Try to get the angle, shape and openness of the ellipses right If you draw crosscontours, remember to draw through here too Spheres (these are the most advanced) - Try to make the contour a true circle Try to get the angle, shape and openness of the ellipses right If you have 3 crosscontours (one for each axis), try to make them at right angles to eachother in space Do your best, and if there is anything you find yourself struggling with, we'll work on it😎👍 I hope this helps :)

Is the assignment to draw the parts (as simple forms) in the same perspective as in the image or do we draw each of them in several different perspectives?

I think the point is to get to know and understand the joints. So you do what you have to get there. Maybe start by drawing with the same perspective as in the image, then try drawing it in other positions or angles. I think Marshall's example videos will give you a good idea of how to approach the assignment. I hope this answers your question :)

These are super crusty, the first 4 I did a couple of months ago and the rest I drew recently. I would've redrawn the others but I sorta wanted to move on with the course :] The perspective is off and lets not talk about the hands and feet...yeesh anyway if anyone has critique it would be greatly appreciated <3

I'm a bit rusty. Haven't done any drawing in a few years now as I've mostly been doing 3D modeling. Feel free to critique. I know I was sloppy. I rushed it a bit. Line work is pretty wobbly with the digital tablet as well. Hopefully I'll keep getting better at it.

Started off the first one copying more than simplifying, then I started to realize I need to care less about exact shapes and more on form and simple designs. I didn’t have much trouble beside the hands and how I should simplify the elbow. It actually was quite relaxing because I wasn’t worried about detail, I could have detailed more if I wanted to, but didn’t feel that was the point of this assignment. Any critique would be nice. I spent about an hour on whole thing.

Wow great job. I think your rib cage is too small, but everything looks 3d so it doesnt really matter.

Im guessing i need to be a lot more careful and technical for this assignment. I have a hard time with more technical drawings and I may have rushed this one a bit. Advice?

It looks like you are having trouble with perspective. Try breaking things down into simple shapes. The rib cage can be drawn as a simple egg with a center line. It's easier to fit the individual ribs inside the egg than starting off with ribs. Also something that might help is to ghost your perspective lines in. See my examples. Keeping in mind the perspective has always helped me in my studies. Good luck.

Exercises for drawing simplified joints and labeling, definitely learned a lot about how my body moves, hope I labelled everything correctly :P

Good Idea to label the joints and point out where they are on the structures! I think that you need to do away with thinking about the contour of these complex forms and simplify them down to the most basic shape possible. Once you have simplified try to take these simple constructions and make them more true to the structures you are analyzing. The key is to make the shape that best describes the form as simply as possible, so going back to the most primitive forms will help you in this regard. This is my first critique so sorry if it's worded poorly or hard to understand or overcomplicated, hope it helps and keep drawing!!

Sorry for the partial unclarity, I was drawing very small on paper. Also apologies for the close proximity of 1 & 3

Nice drawings! Good line work, solid structure and perspective! Good job!

Here’s my joint assignment, I feel like I’m getting how to apply perspective intuitively - which helps focus on the simplification and understanding of the joints :•)

Hi, I’ve just recently got back into drawing after a long stretch of not doing it. I’d appreciate any feedback!
