Sparkling hideout

A birthday drawing for . Some kind of lindworm in his hideout a wonderful cavern with glowing mushrooms and crystals. The poor thing needs a really comfy hideout to compensate his missing ability to fly.
Maybe this sounds weird, but first I just wanted to draw blue light from the mushrooms - then something happened that forced me to let the crystals also glow: I spilled some oil on the picture... oops. Anyway, sometimes a mishap can turn out into a good idea. 

Drawn in 2014
