I think the door is a little more in focus than the little dancer or the shoes. I would've rather had them in focus with the door in the background more blurry.
If you used the timer/remote to take this photo you could've set a book or something on the floor for the camera to "focus" on then carefully set the camera to "manual focus" (without bumping the lens). Now just stand where the book was sitting and hit the timer. I'm probably assuming it ALL WRONG, if so please ignore this comment as I don't mean to be insulting; just wanting to help. -BB
I am not sure where your focus is. Also use a plain background or similar alternative. Try reshooting again but with the background at least 2-3 ft away from subject.
