I adjusted the whites and blacks and I made the saturation higher, I also played with the exposure.
I adjusted the blacks so it would be true black and the white to be true white.
In this picture I adjusted the highlights so the clouds would pop out more, I also adjusted the blacks and whites.
For this photo, I adjusted only the shadows and the whites to make it lighter and make the beautiful view of the sky more vibrant and the pier a little more visible.
Good work. In the adjustment for your own photo, you could also open up the shadows more. it will add detail in the dark areas.
