There we have Chaos and his favored toy, Violência (yes it's violence in PT).

That's a Macuahuitl, an ancient weapon from Central America which is essentially a wooden sword with obsidian razors for it's edge. Except Violência is made from a unlikely long femur instead of wood. Wonder who that came from...
Macuahuitl were known to be frail but deadly. There is a report from a spanish soldier, during the invasion to Central America, of an aztec warrior decapitating a horse with a single hit when the horseman charged in. You can read all of it at Wikipedia.

This is also my first really dynamic and full shaded piece. I'm very happy with the result. :D

By the way, Caos is a character from my upcoming illustrated story, Desordem.
Also I use him as my sona. :3
