I like the lighting on her back.
I don't like the lighting on her face.
I like the angle her back is positioned in.(very flattering)
I don't like that her nose is stealing all my attention. A diferent angle for her head would have been much better.
strange how no one has commented on this post so far...
i'm assuming the tattoo is the main point of your image (based on your post title). the lighting on her face is drawing my attention away, and the lighting on her back is kind of dull. a different composition could definitely draw the eye more towards the tattoo, and so could different editing.
