Thanks everyone! Update!

Tried to make the hand holding the gun more distinguishable.
Nice edit, gnarf, but the hand still doesn't look like a hand...More like a blob? For now I think I'll keep his hand hidden 'till, as Alex said, I pixel a handful of hands.
I noticed the Sternocleidomastoid muscles in your image look detached from the Mastoid Process
Wierd...so wierd that I didn't have to look those words up.

I guess I did learn something from biology class. I changed it, but I don't know if I fixed it. I'm trying to pixel without references, then go back to see how much stuff I screwed up.

I hope the pants and body are more...distinguished from one another.
Again, thanks. I think I'll call this one done for now.
