first torso help

I just turned 15 and i have a lot to learn; i just started figure drawing yesterday. i sketched this torso from a model in the practice section and threw it into Photoshop to add some color and final lines.
Sketch time: 4 mins
Photoshop time: 6 mins

I wasn't sure how the stomach and right breast looked so i wanted some feedback from some of the great artists i know are on this site. Thanks for your time!
