For the life of me, I could not pose the first anatomy fix of their wings. It was too weird. I think this compromise might work. Also got the wing finger actually coming from the hand and not the wrist. Too mammal/bird-like for them but gotta go with what will pose easier a million times in a row. To keep the weird wing shape in silhouette, they'll walk on their knuckles.

We'll see if this works well when it comes to active poses.
