I recently painted up King Starfire. He's a leveled up version of the boss dragon from the core set- and he's a pretty sizeable mini.
I rather enjoyed painting him up, and I felt that the starscape worked very well on him. I used a simpler version of the starscape patterns on the original Starfire's wings, so I felt it appropriate to give this Starfire a more elaborate version.
All together, he's simply huge for Super Dungeon, but we played with him the other day, and he's tall enough that the other characters can stand at his base without any issues.
Here are some pictures.
