@sickelo Really good progress so far. I agree with Yukino’s critique about the teeth appearing to grow out of his lips as opposed to inside his mouth. Simply building up the lip shape in front of his teeth would help.
Also yes to the length of this legs. I know the art cheats his leg length a bit. While it works in the 2D art, the cheat tends not to work in 3D. I recommend deviating a little from the art and lengthening the right leg a little while shrinking the knee bend in the left leg. That should be enough to give the impression of the legs being the same length.
Good job on the primitives as well. Sure it could use some polishing off of the bumps, but overall you’ve fulfilled the exercise. It’s an A from me this week!
