I think it would have been really cool if you laid a white sheet over the tile. Would have seemed more like a studio. BUT I really like the shot and the way she fills the frame in a unique way. Good lighting & colors.
Nice, but I would have liked to see a more edgy facial expression to go with the dominatrix look. If you cover her body and just look at her face and hair it looks like she is selling hair shampoo and conditioner. It just doesn't go with the outfit. Still nice enough for a 6 though.
