i really like the shot. its a nice natural expression, and a nicely off-center composition. for me, the eyes really connect with the viewer, and the depth of field is just right, giving enough in focus, but throwing out what isn't necessary.
the colors, if purposeful, are nice. if not, then you're a little toward cyan i think.
I like it. Nice composition, nice expression, and soft natural light with just enough hint of modeling to not be completely flat (IMHO not every portraits needs strong directional lighting in the Rembrandt style). Nice catchlights too (and pretty eyes). Color balance seems to have a bit too much cyan in it though.
