Design sketch for my seismic/earth/volcanic dragon I am working on.

His working name is Richter. I might change that.

The horns are meant to be glassy black and have almost an obsidian/volcanic glass type look with a polished shine, but they are cracked apart at the tips and superheated rock can be seen. His whole skin surface is not so much scaly as "rocky" in a way, though he has smooth belly scutes. This sides of his throat show hot rock, where his flame glands are.

His teeth and the entire inside of his mouth looks like red-hot rock. Places that move a lot like the corners of his mouth, or his eyes, also show a lot of "melty cracking" effects.

I didn't get around to adding it but he also has a lot of lighter ashy highlights on the higher bits of his scales.

Some of the input/ideas are from the very awesome twilightsaint, who chilled out with me after suiting together locally at Waffle House and discussed this concept with me.
