True Art
An absolute fine job my friend, you sure know your way around a palate. The shading on the cowboy's horse and on the crags behind him really evoke that feeling of a real painting while at the same time creating great contrast with the level of detail, right down to the individual hairs in the mane of the horses. And the darkened sky really reflects well the Iron Maiden origins. But to answer Samus24's question, I don't know that he was really going for a specific tribe, but judging by the midwest-style location it could have been anything from Apaches to Navajos. However, so many tribes inhabited the area that it is hard to say for sure.
