I like how the little plant like on it's shell looks like a large forest along side a mountain. I know there are some other people out there that can see it. Maybe it can be an earth elemental creature.
This.. is beautiful. I especially love the greenery on his shell. Eyes seem to be a bit far forward on the skull, but maybe that's natural for snapping turtles, I don't know for sure. Just looks a tad silly compared to the rest of its gritty, yet gorgeously rough exterior.
