Don't do drugs, kids.
I think this is one of the most dynamic characters I've drawn, and one of the best executed ideas I've done. The background's pretty lacking, but it is supposed to be pitch black, it's just not very impressively done. I've been trying to get better at facial expressions, and this is one of the few I've done that's come out exactly like I wanted.
Seriously tho, don't do drugs. They'll mess you up.
