The main light was too low. Fill is a matter of taste or purpose. When I photograph large subjects, especially women who are weight conscious, I go for a higher ratio, as deeper shadows hide problem areas and slim subjects. Of course, in this case weight is not a problem, but just wanted to make a point of lighting ratios being dynamic, rather than set in stone.
I'd also move the kicker further back, so as to avoid the shiny spot on the right side of her nose.
