IG-88 is one of my favorite bounty hunters in the saga, even though he was on screen for only a second or so and did absolutely nothing. It's the low tech bandoleer he wears and standard issue blasters he holds in contrast to his robotic-ness, that does it for me. There's a unique uneasy feeling and mysterious menace in that.
POST NON-REFERENCE SKETCHING SELF CRITIQUE:
My love of recycling junk into props unconsciously took hold while drawing this one. I don't think IG-88's bandoleer held used D-batteries. I know for sure his joints were not Radio Flyer wheels or giant buttons or whatever the heck I drew.
