Lol!
I did a simple illustrator rat rod truck a while back for a speed shop T-shirt. Had to keep it to as few colors as possible for printing so it wasn't shaded much but it came out pretty cool. It's easy to get the rat look in photoshop but been playing with illustrator a bit to see what I can come up with. Little more challenging but I think it can be done...
Out here in Utah Rat Rods are getting pretty big at the major shows. Some of them look like major piles but some are done so cool you gotta stop and look it over for 10 minutes.
