I am trying to make and test undersea environment.
Here is the finished render picture.

It’s beautiful. Must a lot of particles here…
maybe not dark or not blue enough though, when i first saw it i thought it was in bright day light, then saw the shark.
looks very cool. I agree that it is too bright though. also, you should try putting some particles floating around with some DOF to give it a more soupy feel
You got the modeling and detailing down, now just work on the atmospherics.
Give it a bit more fog and a bit more of a blue-green color (how dark depends on the intended depth of the wreck).
The shark also looks to be a bit too shiny and reflective (looks a bit like rubber). Jack up the roughness, lower the glossy, and maybe add a trace of SSS to make it look more real.
Thanks all suggestion 
Yes, too bright, i made it darker with blue-green color tone, gave some fog on the top, and strengthen the DOF.
Also, added some particles floating, i find many reference but i am not sure what it should be looked like.
Update the picture, and hope u like it.
Yeah, looks much more under water.
Very nice
Great Idea, really like the final image. Too bad cycles doesn’t do caustics better.
wow…great scene…very detailed work
I do love the overall work you’ve put into it, but feels like it’s missing something… either more light in certain spots… and less in others? The model detail is amazing, impressive work overall.
