Valeon tunnel start

As I promised, I've been working. Here's a tad of proof--I've just gotten stuck at this point. Maybe someone could have an idea for the walls?

(Finished piece posted)

I've somewhat darkened Valeon's coloring as well. So once I get the torch drawn on the left side, the highlights on him can be tweaked a little and I can hopefully figure out how to color the walls and that weird looking ceiling.

Sorry, hadn't noticed that my editing things had resulted in this one being deleted. ^^; Reposted the piece.
