The recent Heavy update made me want to do this. First I played around with a more obvious design that was more of a female twin of the male Heavy, but I found that a more distinctive, unique character design was more fun to do.
It was tricky to keep the character female, while making her beefy enough to have a silhouette that isn't all wrong for the class. In the end I went with a big rack instead of a big gut and made her black instead of Russian. I'm not quite sure about keeping the racial/ethnical part of the design fun and innocent, as wih the male Heavy, but I did try.
