This is the best tech demo I've ever seen. I really think you should polish up the caustics on the water though. Something about that room looks very fake :)
Oh also, the layout of this demo's interior reminds me a lot of Halo: CE's Forerunner architecture. Very alien and brutalist.

Thanks for checking it out! I've been meaning to fix up those caustics, but every time I try I end up getting lost somehow...
