Here's one of the commissions I did while I was at HeroesCon just a while ago. I was only doing a very limited amount of sketches because it's really tough when you also have to take care of a baby at a con! I wasn't sure I could deliver it in time, and I was given a choice of either Rogue or Harley...and Harley's my fave character to draw, so Harley won! I remember the guy coming back a few times to check on the progress, and I'm really happy I got it done.
This was piece was drawn in an 11 x 17 sketchbook, using a black and red prismacolor pencil.
