Wow, there is so much interesting things seen and happening here I don't know where to look first! Now this is definitely an interesting place to take a stroll because of all the wonderful things to look at. But I feel you need to give your audience a main focal point within so that it is a starting point/opening point so the scene is not so overwhelming with busy activity. Just as an example, a picture that shows one or two of the museum patrons with open eyed wonder filling the frame on the left third of the frame looking at the sights would give your audience a starting point to then take in the scene at large.
Terrific and terrifying place. What a nightmare! The floor is amazing; all these people walking on water. As a photo, I think that you tried to show too much detail.
