Here's a pair of painted treasure chests in both their open and shut configurations. These aren't board game pieces; they're intended as set decoration for tabletop roleplaying. I'll probably wind up offering them up as set dressing for the Villains and Vigilantes game I'm participating in.
As you can see, I'm still having a hard time colouring between the lines at this scale. On the other hand, I had to experiment with different colours to get the gold doubloons to turn out, and I think they did!
