Are you wanting C&C? I'll offer my initial impressions if that's ok and these are only my opinions.
Awkward frame, pose and expression. I may have stepped back and taken more of her into the frame for some sort of context. If a headshot was the intended goal then perhaps not having her arch her head as such and add a mischievous smile, it just looks uncomfortable to me as is.
Lighting is ok as far as angle but perhaps slightly higher, then again the pose could adjust for that.
She's a beauty and I'd like to see more of your work with her!
