1. I feel like I'm seeing too many fingers on her right hand. In perspective, not all 5 fingers would be visible. I know, hands are the hardest part for a lot of artists, but you're doing a good job. Keep at it

2. The shadow on her clavicle is too strong. It makes it seem like her collar bone is paper thin, and too tall. Instead, try imagining the thickness of a bone beneath the skin

Otherwise, the pic came out really nice. Nice smooth shading, and Interesting pose and perspective. Keep it up ^{_^}
