This is the artwork I want to put on my arcade.
I got photoshop 7 to try to fix it up, but I don't have a clue what I'm doing. Only thing I can do with photoshop is put afro's and bushy beards on people, aw yea I'm cool

.
Well, I was hoping somone here knows a bit more than I do and is also willing to give me a hand. What I'm wanting is the lines to be sharp and the colors solid or more painting-like.
If you feel like giving it a try the picture is here:
