Nice take. The curves really dominate and set off the people nicely. I've been to a few aquariums like this, but I don't think I've ever shot quite that angle. Good eye.

All around a strong image. I love the mystery of the water above these people. I can make out shapes, but only one distinct fish. Cool shot.

I so wish the top of that tunnel weren't cut off.

as a tunnel and with forward movement, this works very well. as for curves, well, a bit stretched. very nicely executed though, probably not very easy lighting
