Over all I am a BIG fan of this look. The only part bringing it down the is the mask, the hooking nose and smooth head, meant to resemble an American Bald Eagle I am sure, looks too much like animal furry cosplay. Making the nose/beak less hooked and maybe flaring the sides of the mask Hakwman/Hawkgirl style might offset the look. Again this is merely personal taste and nothing more. Overall I like this piece.
Sadly I have to come up with another 20 words to end this critique, I feel like I am in high school again.
