It's a good shot. Lights and Shadows exalted a nice body. Soft, good focus, mysterious...
Technique are good. Model is very nice.
Piercing give at the pict a little trasgression: good.

I appreciate the cut... a idea of unfinished... very good.
I also often use similar cut.

A single defect: originality: unfortunately a nude body is a difficult and too used theme but... dont panic, it's a very nice shot.

I hope that this modest criticism welcome
and i hope that there are too many errors in English

I hope to see this picture as a favorite of the day
