This is amazing, but you use a reference? If you do, hopefully you don't actually but fish in such a small tank to take a picture of them. That certainly wouldn't be fun for them. I hope this comment doesn't offend you, your art is beautiful!
OMG.... first I was thinking about, that for photography, you must put the fishes from one place to another regurarly...I was wondering how you solve it that they don't die from that..than I looked the category and I was like..omg o.O this is not a photo of real fishes. congrats it's awesome ^.^
I'd really love to see one of these with bubbles or surface ripples or something to describe the motion in the water. They're amazing and beautiful, and I watched the video so I do understand how hard they are, but they're so very very still.
