Environment-Fish tank (WIP)

[divarch]

Hi there, here I go again with my underwater subjects... must be something sub-conscious since I won't go on a vacation this year. :)

OK, I started a fishtank model, so check it out.
It is not even nearly finished so focus critiques on light, colors, and overall look. Also add some suggestions of course, about what kind of 'life' should I add.
I was planning to make several types of fish, and add some bubble blobmeshes, and revert the treasure chest into a respirator.
All things modeled might look like under ocean, not for the fishtank, but I used reference images, and all kind of rocks, corals, and foliage seems acceptable.

How's the color balance? Does it look lively enough? And any suggestion about the background ?

Please, all C&C welcome!
Thanks

OK, so I will have to talk to myself...

Here's lastnight update.
With finished tex on a big rock, along with it's growings, made coral group to the right, changed filter tex&col, added more shell-coral like life (yellow and grey one's)


Any c&c welcome!
