I love this artistic portrait! The lighting and composition are great. The muted tones enhance the feeling nicely. The treatment brings out the zigzag form of the body very well.
I wondered a long time about the cropping of this image, with so much space behind you, even made a different version and I found the extra space is very, very good, becauze the direction of the eyes needs it... compliments! The alternative version is added for reference...
