I love the ambition! Very fun piece with both detailed clothing (great design btw!) and accurate anatomy. The only thing that really bothers me is the framing and background. They really do not help your piece and in fact only bring it down. As a last note, I suggest not leaving your lines black. They could be so more dynamic if you changed them to brown, for example.

Looking at your previous art this seems like quite a step up for you though, so well done! ^-^
