This looks fantastic !!! i like it very much. you seem to have no problems with humand or animals drawing. you are so much ahead of me. I need to train harder :D. only thing im not sure about is the black you use for the shadows on your cheek and body. i would try to made them softer, because it looks like a beard ^^
to each his own! Personally, I do not see any flaws!
my intention is not to moan, i want to help here. but like you sayd its only my opinion
Thank you!
