Okay here is my (I think) final concept. I had started 3D blockout, but forgot to take a screengrab before shutting down last night. Ooops, so I'll post that up soon. Hoping the little robotic arms, weapons, and tech-y looking eyepatch... make him sci-fi enough? I added a riot shield on his back... Think that could look cool.
Think the smaller gun could do with some more thought. But it will probably easier to do that in 3D.
Thoughts?
