The problem with the nipple is that you drew it like it would be on a woman's chest. Nipples on muscular males are not drawn in the center of the pec. They are drawn near the bottom and usually near the bottom + arms. It's not as though I pay close attention to that or anything. (hahaha) But when you learn anatomy for drawing bodies you need to know this stuff.

As an exampe I've chosen Lou "the hulkster" Ferrigno back in his Hercules days.
