The light on her face is nice, but I find the composition unbalanced with the arms at the bottom and how unevenly lit your sitter is. The bright light on the arms and hands is distracting.
I do like the negative space up to the left, which pushes her into the frame very nicely; there is almost a sense of direction which jives with the direction she is looking in.
Thanks Thomas for the comments. I burned and burned the areas you mentioned but the area goes muddy fast. I guess its time to either look another neg or "gasp" go digital!
It's interesting how much her face takes my attention to the exclusion of whatever technical flaws there might be. I've been interested in her and her work since I fist saw some of it in a B&W magazine some years ago.
Thanks for the portrait.
