Quite imposing!
Interesting idea. I like how you incorporate the lines for wire and cable extensions. I also saw the Contemplator and have notice that the form of sketchiness is pretty good.
If you ever like to incorporate some human elements, you can do comparisons on human skeletal anatomy and the joints,gears, and moving parts of machines in which comes close to relations how movement works. Like for example, what artists did during the production of Terminator. I actually know a good reference source from a popular artist or artists from a book that does illustrations on cybernetics. I'll look for it and PM you the link.
