(For the weekly challenge)

I'v seen the colors of the challenge and with the fact we are talking about robots, I couldn't resist to make a use of Blitzcrank from League of Legends.

Blitz is known to scrach in his head when you are not doing with him anything in the game, so it really fits into the Nervousbot description.

I'm still new to pixelart, and the work here was really hard since the colors I used for shading are not really easy to use.
