It's look very interesting and the most elements are very good animated. Perhaps the lightning must down more fast and the windows down in a "hard" way.
And this is only a personal opinion: I don't like so mucho the gradient of the wall and floor, It's so hard, personally I prefer the gradients more blurred.
Good Luck!
