Really cool comp, you may define a lil more the shadows, like the hair, in front it's directly exposed to the light source, so is lighter, but the hair on the back side of her head should be a lil darker, also the lightnings could fit better on the backgroung and not directly in front of the model. "just my thoughts"
Sorry Belial; I really was just joking. I was pretending her wide eyes were because a spider was crawling on her. No offense. NOt really feedback, certainly not worthwhile feedback. I'm gonna go put on the dunce cap now.
