This is breathtaking. Awesome in the purist definition of the word because this truly gives feelings of awe. An absolutely monolithic megabot super body worthy of any to call themselves a Great Spirit.
I could easily imagine this as a titanic robotic being that went into hibernation many ages ago, only for a race of smaller beings to build a sprawling and expansive fortress around his slumbering form. Living there for generations until nothing of the original body can be seen. Then one day this ancient entity awakens and stands up, covered in overgrown foliage and castle bits. Instead of panicking and abandoning their home the inhabitants adapt and build around the standing titan. Living in and around it, keeping their waking fortress ship shape as best they can, forming a sort of symbiotic relationship that's lasted for generations.
This really is stunning, and I have nothing but admiration for your commitment and dedication to this project.
Do you think you could post a full body shot? The entire creation head to toe in a single image? Is that even possible?
