your proportions on don-kun are far more accurate than with your leo drawing, and you weren't shy about making DARK MARKS! proper shapes come with practice, but i really DO like the diagonal layout and the active pose! you've got great ideas.
This is a good pic, but methinks it's Donnie's LEFT leg that needs work. No offense intended, but it looks rather odd.
ah very cool, the right leg luks a little wobberly, but nice picture
