Finally drew the rest of this thing, in all its awkward glory.
(Previous pics: part 1, part 2)

You can tell it wasn't really built to be walking around like this, it's built for flight - but I do think it was actually built, it's at least partly biomechanical in nature, just closer to the 'bio' end of the spectrum than your typical aeromorph/LM-type thing. Probably lab-grown, then modified after the fact.

I think this design could still use some refining, there's a few aspects I don't think I visually communicated too well, and some parts of the lore/logic that I still need to reason my way through to figure out how to visually communicate them in the first place. And some things I just need to push further, exaggerate more, etc. But I'm happy to be finally making some progress getting this vague idea out of my brain and onto a canvas.
