Trying out a foam idea.

The foam looks like clouds for me...hmmm...otherwise I really like the rest of the setup of the render :)
I agree with Archonforest: foam is too irregular; exept that, the island/the coast is very cool !
No idea how to do it so no advice. But I like what you got so far.
A closer view of the shore. Still working on some ideas about top foam and "underfoam" (the tint you see when a wave has submerged a lot of fine little bubbles). Dropped the small amount of wave warp from the previous render waves as this probably added more unreal bad qualities than good.

I like that idea of underfoam, have been working on that lately as well. I changed the color of the water density color to a quite blue blue, that looks quite nice. Then the 'real' foam on top.
That crop render actually looks pretty cool ;)
To my eyes the water looks a bit too gelatinous as it is now.
