It's a redraw I did of another concept which I did a few days ago. Frankly I thought that the original sucked so I redrew it in a new pose, and put more thought into it.
The idea is an alien cyborg whose arm has been damaged badly and has had a weapon grafted onto the end. The first one had one whole arm, and I switched this to the other side in the new version and made the cyborg arm have a really large cannon attached to it. I still have no real ideas about what the cannon should look like though. I did a quick tablet sketch in to show where his legs are going to be. The idea is that he is sort of sliding down a dirt slope and the dirt is piling up in front of his feet, (but I got no idea how to draw that actually!) I have no real ideas about his left arm.
Here is the new one:
and here is the original (I'm not sure if this violates the one pic per post rule, if so I i'll get rid of this pic):
Rip it up.
