Figure drawing practice

This is two sessions of figure drawing. The first session was the introductory work and builds up, and the second is a regular 30-min class. I look to eventually stylize my anatomy for my comic book, but am looking to fully understand gesture and anatomy along the way. Funnily enough, it seems to me I am better at realized drawings than cartoony/anime ones.

First I would like some general critique from these two sessions like whether the proportions of anything waist down could be improved and how? Second, is there anything I can implement at this stage to help improve stylization? Or is it just repetition until I understand?
