you feel your picture looks wierd because A) there is no body hair of any type, or details of the eyes and nose, which is good for purely shape related studies. B) Your female figure is out of proportion on three things, which is throwing you off. 1, her breasts are placed too high in relation to her arms. 2, her rib cage is too narrow. If this were a living human she would have difficulty breathing, which is setting you off. 3, her groin is set to high in relation to her hips. This makes her legs look longer, but would mean in real life she would have a malformed pubic bone. Your male figure, on the other hand, is very well proportioned.
