Your understanding towards anatomy has already grown :P

thanks n.n

like the shading technique ;) im still learning coloring digitally, though, I think I have anatomy down. Tips on coloring please? :P

I find that how the shading turns out is very much dependent on how well you understand the subject's figure/anatomy :/
Tips on colouring? mm, don't use pure black to shade. Using dark blue in this pic made the colours more vibrant. I'm trying to learn from this artist (http://pingagirl.tumblr.com) As for the technique: Shaded the whole figure first, then erased on the muscles with a opacity pressure brush. Think it worked pretty well, you can try it too :D

will do n.n
