How is that related to Metal Gear? I can't see any resemblance.
I love the background and how it is desaturated. The design of the machine is very interesting, but I feel that the lower side of the body has not been defined properly (I fail at grasping the shapes in that area). It is very nice over all.
Great job here. Do you think the pink lighting on the underside of the main body should be that bright? Comparing it to the leg which is near the source, it seems strong to me. It's hard to say since I've never seen something like this in person
