Some good contrast areas. The coloring of the face and skin seem...hmmm...I don't know...too muted in tonal values which for me, subdues some of the overall contrast. (I'm not too good with techincal critiquing - just my lay person's opinion).
There's a little too much light reflecting from her face, IMHO... that might have been the intention, but I really think it doesn't work very well in this kind of portrait.
wow, I like what your trying to do here. the only problem is the exposure. the focus is wonderful but the blacks are to grey and the white are to gray. put the camera in manual and take the meter readings yourself
