As details go, I’ve added the snake (which may or may not be alive, wink wink), an altar with a “jewel” on it, and the mountains and boulder.
There’s far more I could add, like a ruined path. Materials have only simple colours, as I don’t know how to add textures yet.
I’m not sure the lighting is right for it as is.
Don’t steal the jewel, it’s not worth it.
