It IS a magical forest. Very beautiful! HOWEVER... "Both (land and water areas) MUST be a well developed and well planted part of the whole design." As a result I have had to mark this wonderful enclosure way down. The water area is not planted at all.

This is clearly a well designed and mature aerial display. Given the overall size of the installation it's clear there's a large volume of water. While you showed a picture of some of the fish they're young and impossible to see in the overall image. Having large shoals of the Rainbows in the photo especially once they're mature will help to balance the overwhelming aerial section.
