Tex Mech - Sheriff Junk

Here is an ilustration I created for Crimson Daggers Bloodsports 9 challange - "Tex Mechs". My idea was to build a steampunk-like robot from some rusty, metal junk pieces. I asked Bjorn Hurri for crit and he said, it's a bit hard to understand how those pieces on the arm and stomach work. I guess I made it a little bit too random. I'll think about functionality more next time.
