In the meantime, here's some doodling Woodrow Phoenix and I did on the train ride back to London. I was telling him that Gary Northfield taught me how to draw Batman last weekend at Hi-Ex. But then I only got as far as the head before I forgot how to draw the rest of him. So Woodrow drew Batman on the right side and I finished on the left side.
Woodrow says mine's actually the Joker in disguise.
