Nice color... I wonder if a bit of corpping might not add some interest. Of course if you ask three different photographers how they would crop any one image, you will probably get three different ideas.
However I would crop both the top and bottom of the first two images making them look more like a panorama. I would crop the third image through the overhead board on the pier sign and on the left through the piling, effectively making a frame from the pilings and the back of the sign.
Hope you don't mind but I tried the different crop on image #1.
