Ancient Aegis Tower Mk II, Work in Progress

I'm quite taken with this ancient, but not ancient Steampunkish tech thing, aren't I? Here's a couple of work in progress shots of the latest. Blender's modeling tools are so quick and intuitive, I find myself mostly sketching in 3d, these days. I'll upload the finished scene, soon. The original, that got the ball rolling, is in the link.
