Water Altar

Decided to make altars of every element, I got quite problems doing this one though, because is not so easy to make underwater things. And I'm not still sure if it looks underwater, so what do you think?

Sry, dude, but this doesnt seem underwater at all.

Anyway, This will help you: WT 13 - Final Entries

better?

Good, but remove the red in the fog: Red light barely penetrates the surface of the water, and this looks like it is located in a rather deep area.

yeah, make the fog look more deep dark gray/green/blue

Also, make the fish school together
And maybe you also could use some custom models.
