What a beautiful concept. This is the kind of work that makes me think "Why didn't I think of that?" I've been to the Bellagio many times, not as a guest, just to use the VIP restrooms in the lobby (gold plated handle faucets, marble floors, huge mirrors), fit for a king.
As impressive as Bellagio's real fountain chor., you did a very nice job choreographing to the choice of music. And adding color to the sprites was a nice touch. As I remember, the fountains at Bellagio were lit with more of a golden color lighting than simple white.
Also, something about the girl's front bangs that didn't move quite right at the end.
Very nice work overall. Present it to Bellagio! Who knows, maybe a paid job will come out of it
