Just finished painting a 6mm dragon from Perfect Six Miniatures. It comes from their Order of the Dragon fantasy range and should have been the Black Dragon Ashmar. But I chose to paint it red. He, or perhaps she, (I'm unsure how to tell the sex of a dragon) works just as well in a dungeon crawl as a 28mm baby dragon.
A "6mm" dragon.
