An underwater map, any tips/suggestion?

Does this look good?

I think the fog is too thick and blue. Perhaps it should be a little more like in this tutorial: Underwater effect for maps

Also, I like what you did with the ruined column at the upper left of the scene. Nice use of in-game models!

Lighten up your fog. I wanna see fishes and whales and things swimming about! Octopus lurking within! Mysterious mermaid signatures!

One thing I'd point out is that your underwater structure has too much 'structure' and too little 'underwater' in it.
You should add a lot more fish, bubbles, seaweed of all sorts, corals of all sizes, etc. Everything that can be seen only in underwater maps and nowhere else.

1. I'd also change the fog color and its thickness, it's really important to get it right. Try to play around with it until you think it looks the way you need it to.
2. Add more things that stretch upwards, it would add the feeling like you're actually under the surface of water.
3. If it's not a playable map, then try to get the right camera angle as well.

You should absolutely check out Player_72985's methodology on underwater scenery. For years, it was one of his specialties. I suggest you check out his Waves Of Blood short cinematic:
