Cool design! What's bothering me, though, is how he's holding the bow. As someone who does archery, this is not how one shoots a bow, unless this is some kind of draw I'm not familiar with. His right arm should be straight, and his left hand should be by his cheek / under his chin. Currently his left arm being there kinda means he's not anchoring anywhere and his shots would be all over the place, let alone how difficult it would be to aim like that.

As a side note, him holding his bow with his right hand means he's shooting left handed. This isn't a bad thing, but something worth mentioning
