The piece is excellent and the shading and coloring compliment each other well. The anatomy is on point, although I feel that the wings might be slightly out of proportion with each other. Although the composition has a minimalist style that fits well with the piece, I feel that for it to really complement the piece some things need to be shifted around a little. I would find the piece even better if the two circles in the top half of the piece were higher up. I feel that in the place they are now, they kind of detract from the wing's beauty and sort of swallow it up. Other than that, this piece is wonderful and I hope that you continue to produce pieces of this quality.
