CPL, use one.

Clean the dust off sensor

Pick a better day, light is everything, find the time of day that the DR between the burn out sky and the shadows are closer
Wait for clouds
When you have about two stops difference, you get good separation of subjects.

Maybe use a graduated nd to kill the burn out on the left side of the piers.

If you are using light room try this, reduce the highlights, increase the light in shadows and decrease exposure.

First picture doesn't look in focus.

If you under expose it is easier to fix than if you burn it out.

Your top subject has the most potential for a great picture IMO.

Good Luck
