I've had way too much real life getting in the way lately, but I just wanted to say that this looks really great. Fantastic use of architecture, lighting, and detailing, and lots of Z.

I also like that you went the extra mile to get the bots playing nice.
If you want to get rid of the visible patchmesh seams on the curved construction under the bouncepad above, it's easy, albeit slightly tedious; just flatten out all seven(?) meshes so that they're all coplaner with the brushface that's in the middle, match them all to that face, and then bend them all back into place.
As an alternative, you could probably do it all by specifying explicit x/y and correct rotation, but I always found it easier to just flatten them out...
