I think I would prefer this shot if the focus were on the reflected face. My eye keeps darting to and fro between the two but the balance feels off when my eye keeps wanting to rest on the left edge. On the upside, the lighting is spot on, and I love how the purple backlighting matches her make up.
Those eyes are amazing! But there is something very plastic about this image, perhaps the overly smoothed skin? There is also something very vapid about the model's expression, although the reflection is much more vibrant and life-like. This almost led me to think they were twins :-)
I don't think the expression fits. Alice was never particularly happy in the story. She was usually surprised, confused, upset, or lost, so I would have preferred an expression that matched one of those emotions instead.
