I did a Batman sketch cover and my friend said I could draw any BatUniverse characters, so naturally, I picked a couple of the girls. PS. I added the purple, orange, and yellow in Photoshop, just to spice it up a bit.
Calvin (of Hobbes fame) used to have entire strips dedicated to an imaginary character, a space captain or some such. I am still very much in favor of one of the girls having super-heroine daydreams in Outnumbered. If only because I want to see more of your super drawings!
