I think the camera on the crotch is because it is pretty tall so it has to make sure no small enemy escapes by running through the space between the legs, or to record robo-porn. And the rope/chain coming out of it's butt is actually one of those ropes/chains that you attach to a car to pull it, or maybe he uses it for robo-bondage.
A few questions. What is it armed with exactly? I see the chain rifle on the left arm's ammo. What about the right arms ammo? And is the suit able to drop the chaingun? Also, what is that next to the left arms ammo on the shoulder? Flares? Grenades?
I love this design btw. I'll have to use it as a description when I need a mecha for a pencil and paper rpg.
Great work! i just have this little thing with my artwork (i try to visualise it in the real world). n ur case, even though it looks EPIC, it would be hellishly untsable -maybe larger feet (like the matrix/zion APUs). Meh, good job
