Digital Drawing Example

This is interesting. I'm doing a waist up picture on a muscular male as well. I thought the head looked too wide and short, but your head looks nearly identical to mine except I need to work on the eyes and nose and then it won't look like his eyes, nose and mouth are too small.

Edit: I fixed the head, but the head doesn't look like it fits well with the body. How do you do it? XD
