I guess you don't use any reference cause it doesn't have the realistic porportions from this view what a female body has....(maybe you can upload some other angles of the body...) but if you are going for just a character than your on the right road! and oh...send us a image in polymode..that's allways interesting to look at!
catch ya later dude
ps. I see you have photoshop so it would be better if you would cut out only the important thing (the body)...would be alot better to for the ones with small broadband..
