Dragon Egg

And attempt at the "Draw a Dragon Egg" prompt at Daily Drawing

The idea was that dragon eggs are black on the outside, but if you carve into them, and particularly if you put a light inside, you can get red-orange-yellow layers...
Sort-of inspired by seeing carved emu eggs.

I'm not yet up to painting stuff like that digitally; in colour pencils it might have turned out better. I don't think I'll try to finish that.
