The blurred background disconnects your character from her surroundings somewhat. I'm not sure if that was intentional. If it was it is an interesting isolation effect that works nicely with the blues in the work. It seems kind of sad.
If it wasn't intentional well, you should fix that. It sort of seems like she's just been pasted on top, like she doesn't really belong there. Like I said that could work, but not always.
Still it is a lovely piece of work. I do like it very much.
