Thank you, I believe i should give some search around the web and study the human body a bit more :P and prob update it later with a background or use the tip to my next piece

Lol when i was nearly dne with it I thought it looked like her a bit as well xD

at first glance i thought it was amy winehouse. Looks nice bit a bit off at the same time.

Breasts and belly are ace!

You worked well, but some things need improvement:

You really need to study bone and muscle structure of shoulder area - it looks wrong. She looks like she's playing tennis or volleyball, so in sports photos you may find proper reference for exactly this pose. Also boots leave a lot to be desired  and hair flowing forward, not backwards, looks strange. And some nice background wouldn't hurt.
