Don't do it....it's DIP!!!
Yep, here's Judge Doom, the baddie from "Who Framed Roger Rabbit". This was done for March's Disney Villain theme for PLANET PULP ([link]
This was a fun one for me...one because it was fast..it only took me a couple of evenings to finish...and two, I used a combination of warm gray and cool gray Copic markers. No photoshop! I like the subdued colors...don't you?
