Background is too far out of focus to make DOF useful in this image. As it is, it's a face against a [slight] collage of colors. Bringing the background into better focus or adding something more colorful would've helped.
The face is slightly yellowish. It would have been nice to have a catchlights in the eyes or if the eyes were slightly brighter. I think the face should be a bit brighter.
It would also have been nice had the background been more interesting instead of almost totally white.
I like the composition though.
