This one is sort of an earthy counterpoint to my previous picture, and I've been considering using it for Silicon, but even quartz is SiO2, so it contains more Oxygen than Silicon. Silicon is the second most abundant element on Earth, right behind Oxygen. Maybe this should actually be the elemental dragon for Oxygen, then... ;)
I'll have to think about that.

Anyway, I tried a new experiment with painting over some of my line art on this piece. I'm rather pleased with the end result. I really want to practice more, and push my art farther. I'll probably make some more speedpaints soon, to experiment and help refine my methods.
