This is a ocean render I worked on all morning probably one of my best Renders. 
Not bad 
I would highly suggest turning up your water reflectivity, that would help a bunch

Use this build with ocean sim to create realistic water

also try to make water material transparent, it isn’t rock)
Beautiful. I like it
Pretty good for an ocean render.
The sun looks a bit fake though, try using glare to create streaks and make it so that you can’t see the clouds through it.
I do use the glare node but im having trouble with the streaks The come out looking realy fat and short how do i fix this? sorry for my bad english
It’s probably because of the size of the sun. Try creating a new render layer with a small shadeless white ball where the sun is and apply the glare node to that, then composite it over the main layer using a mix node.
