you need a shave. a leotard would help making your butts looking more curvaceous, at least it does to mine, which is one of the reasons i like yoga and aerobic.
your butts is sticking out and you tightened your quad on impact. you are doing the difficult approach too soon. try with one leg in front and one leg back first. once you get more comfortable with that then slowly moving the rear leg forward until they are parallel. "why so serious"
