Undead Western Key Art Scene and Character

Here is a variety of concept art that I'm currently working on for a skeleton cowboy character that I created named, Rufus Bohanon. Rufus lives in an undead western town named, Deadrock Gulch. The undead who live in the town are alive from the power of an ancient crystal housed in the mine next to the town. Rufus wants the power all to himself, so he's adamant on keeping the crystal.
