Woot awesome fish bro, I like the render alot only crit is the teeth of the fish I think it would have been better with another shader.
Great job though
realy nice
my critics
the water depth should be more washed out with blue in the distance.
The rocks and maybe the fish must receive more refractions from the watersurface whe the sun goes through.
Maybe visible like this

Wow, very cool work! 
Loos like a cool Story!
Nice piece - .
Did you model your bubbles, composite them or use particle flow?
Thats awesome! I agree that you need more refractions and blur to really get an underwater effect but as a whole, fantastic scene. Did you model the divers as well? it would be great if you could post some renders of just the models.
Congrats on a successful realization!
Liking what I see!
Cheers and be well,
