I think you should take off the tech arm it just looks wierd to me, I actually like the text you have right now but if you do want to change it I suggest script maybe scriptina or something. Where did you find the brushes you used on the right.
Lol, keep the metal arm that u have on him. Makes the sig look weird yet interesting to look at. I like the way u did the brushes on the right hand corner, the colors are bright, but not too bright^^; Another awesome job well done Springs.
