Very cute but I think you should make her look more stocky since reptiles don't have childbearing hips. Also, the curved-in plastron is actually a characteristic of male turtles, while the females are flatter. This Venus looks like she would have lots of digestive problems.
I based her off of the style of the show, which had some seriously wasp waisted women. Looking back I should've made her stockier, and yeah I think ALL the women in the show had some serious digestive issues.
