An Unknown Battle 'Bot

This character doesn't have a name, but she's a robot. Despite the fierce weaponry she carries, she actually doesn't battle much. She uses them more for self-defense more then anything... That's all I've got. She was more of a spontaneous doodle then a character with a story.

Any suggestions for coloring schemes? I'm not a fan of leaving things plain...

Oh, and please pardon the random gibberish to the left. It was some notes I was leaving for myself.
