The white background is the only area that i would really do it differently. i am not sure about the set up during photo session but the current white background is looking very flat, dull and 1-dimensional. during photo shooting, try to move the tank away slightly from the background wall, a 15-20cm gap would light up the background and give it a really nice 3-dimensional effect. If a white background paper was used on the back of the tank glass, don't do that. Stick the white background paper on the wall (15-20cm away from the tank) and not on the glass directly. i have to emphasize on this point in depth because this is the only thing that is causing this beautiful creation not reaching its full potential in a photo contest. all the other aspects of the layout is near perfection.
