It looks great. Congratulations!
From the years in this forums seeing shader collections rise and disappear which where nice lookin, but too slow and/or with lack of usability I'm a bit concerned about the framerate and how useful it will turn out while attaching it to a whole level.
I don't want to bother you. It actually looks fantastic.
For presentation and further tests, I would recommand you to collaborate with others from the community to get at least one nice scene with almost all features, with shadows, differently dark, with color lights, warm sunlight, cold light in a cellar...
Maybe, with a log-file which saves all the test values on the pc where it runs as a demo which the testers can sent to you to give you precise feedback.
