I like it. Something strange about the pose - but the more I look the more interesting I think it is (though I must confess what caught my attention to begin with was her legs ) Her hair is great, facial expression lovely - very calm and composed. The white thing in the background looks like a door, and if you begin to imagine its a door then it means she's a giantess (which some people might like the idea of). The high-heels add to this effect of course. There's no particular reason why anyone would stand against the wall like this in real life, so all these little things make it slightly surreal and intriguing. I don't know if that was your intention, and it doesn't matter to me; that is my interpretation.
The background is boring and too busy, the lighting is so so, but there is something about the color of her hair, contrasted with black clothing and the color of her skin along with the angle that draws me to this photo
