Should have just a bit more dustiness to it. It looks too video-ish, like it was done on a film stage rather than a backlot where you have dust and more natural lighting.
I really like the piece. The model is great. I like the composition with that ground camera view. Your field of depth is a little goofy and I'm trying to work out in my head what your camera was looking at. You got heavy Gaussian type blurring and that's cool as it's on the move.
I think I know what's tweaking me on this. It's too crisp. Tweak the ambient and SSS and it's a real winner.
My apologies for the critique when you did not ask for one.
