No one move! I dropped my brain.
At least, I think that's what this is supposed to be. Some robot dude looking at himself as he feels around his hollow head? Kinda creepy...
The titular 'error' I suppose being that its brain is missing? I'm not at all sure what to think of this. But your textures, colors, shading, etc. are all well done.
Good work, keep it up!
