First and second drawing....Man arms, Man legs. Top of chest (not boobs) too big. Face, head, hair neck real good in all three. Better definition of hands / fingers, feet / toes....but need to minimise (make smaller). Shorten thumbs. Chrissy has a drawing around here somewhere of Alexa that has well proportioned feet.
The third has a lot better proportions in the upper arm & chest area. That's the one that looks the best. The big eyes in Drawing #2 really 'Make' her character, I think. Gives her that 'Look'....
