This is a recent commissioned piece I drew up for a nice fellow who asked for Green Lantern or Doctor Fate. I threw in Superman and the Flash for the extra "Superfriends" feel, but being the geek I am, I decided to draw the old "earth-2" Superman (fellow geeks will get it). I think I just like the idea of drawing Superman with grey hair.
Anyway, the drawing was done is markers and then scanned and cleaned-up in photoshop. The original colour was green (surprise), but I changed it up for variety's sake. Below is the original small pencil rough.
