The romance book cover's woman has a victoria specific armpit to chest  distortion that looks very unrealistic and could have been postworked.  Her skin texture is not as detailed as the man's, and I think the lighting/shadowing on her could be improved somewhat.

I usually don't spend that much time improving the fine aspects of my renders as I do them for my own entertainment, but I'm sure if I were given a commission I'd be willing to spend the extra time.  I wonder if I could make some money making romance novel covers?  Does it pay well?  And is my art good enough for the job?

Any advice?
