Cool! Very unique! 
Thanks, glad you like it. 
Derek wat programs do you use to create your art?
I dont have anything besides MS Paint but my lil brother soemtimes lets me use his Photoshop and Illistrator, Im a noob at them tho.
I use Photoshop CS2, which is the newest version out yet, if I'm correct. Proto Zone and Maintenance Man have been done completely in Photoshop, sketch to color. Sometimes I scan my work in, however.
I have Illustrator, but I don't use it much.
I think it came out pretty well. Hope ya like it, Doc Boy!
