This model has a belly which is hard to draw, and that belly is different from women, because it can't bend when the upper bends, it looks a bit wired and unfamiliar to me, so this misleading me to make sure the position of spine, and that made the result very funny, obviously I need more practice so that I can understand deeply of structure of body, people have different shape, so having a solid foundation so that I will not draw them in wrong structure.
