I have a cool portable drawing desk someone made for me at my local art group. It is very useful! It's basically two pieces of wood with piano hinges between them, then another thing that swings out for the stand. The bottom of the back has grooves on it. And there is a small piece in the front that holds the paper steady. I love it!

Batman's uniform needs some doing, but I find he's a bit harder to clothe as a bumbly relatively shapeless critter.
