The model looks good from the profile view, but the front has a few issues. The hips are too wide, making the area between the legs too big. I don't know if you just havent added them yet, but she needs some shoulders.
Also this may help. A human figure is usually 7 1/2 heads tall, but alot of people prefer to work with an 8 head guide. For a "voluptious female model", i think 8 heads would be fine. so from a front view, the lines that divide your model into "head lengths" would be first at the chin, then the nipples, the navel, the bottom of the crotch area, above the knee, bottom of the knee, lower shin, and then foot.

anyway, hope that helps. keep up the good work!
