You know, I did actually notice this! It's especially funky looking on the characters with extremely large chests, and then a flat behind. However, the tone of your post is completely over-dramatic and I disagree with 'doesn't look female' - some ladies do have a flat behind, just because it's not the idealized female form doesn't mean it's 'not female'. I do think more customisation options aside from chest size would have been nice, personally I would have liked slightly wider hips and although I chose the smallest chest size for my Highlander it's still not as small as I'd have liked, but at the end of the day it isn't a deal-breaker for me.
