This thing is over a decade old now. I put it in storage last year and got it out today to take pics of.
The color was one I custom mixed. It's just that cheap craft paint you can get at any Wally World or Michaels, but it's low-odor acrylic and shoots well out of an airbrush when fresh.
I left out the HARRR-ible Vader figure that looks like he's takin' a double-duker on the can....
There is some light weathering using pastels. Panel lines on the ball are scribed in with a dental tool and enhanced with mechanical pencil.
