The only thing that's wrong is that the shirt was too close her skin tone to begin with.
I'd say you isolate the shirt and change the cloring, it looks too muddled. Other than that, it's cool. Very stylized, but if you like it, then right on.
I like it. The colors are strong, but its like if you were watching a movie and you had a photgraph and over time, is metmorphasizes in to a hand painted/protrait work.
Somethin about it thats cool. Maybe her eyes in the second one.
