Love your composition here, man. The mood is excellent and I like the change you get here to a more natural background. Great expression. Oh, and I like your use of a white fuzzy thing (as opposed to my black fuzzy thing that ended up with very little detail).
I saw the hand mentioned. The skin is blown out along her chest and left arm. Technically, you have a somewhat strong horizontal object intersecting her head. It is a little distracting to me, but not too much.
Hope this helps. Ok, I gotta get running harder.
