I tried varying the position of wings. Most of the time, when I draw wings, I have them folded in. It seems it s much harder to get the shading right for open wings.
My coloring got a lot darker. I screwed up on her profile. The lip area looks wrong. Her left shoulder plate is also off.
At least this looks half decent.
Nice details, and cool picture
Just wanna ask, is the linart done by pencil?
