Best way I can think of doing Deadpool, I'm sure I could have edited it in Gimp to make it look a little bit better but meh.

I went for something a little more minimal and simple.

Not being familiar with the character, I looked at a bunch of stuff and the costume varied quite a bit.
I just much prefer the characters be made to be not facing straight toward the viewer, but a bit toward the side; not just the face, the whole body.
