Nice pick Mike thank you for posting.
I like this image very much and not a lot needed to be fixed.
First I cloned out the part of a man on the left edge and a small boat on the horizon to the right. I then used some luminosity mask and the color balance tool to bust a little color in the shadows, highlights, and mid tones. I used the curve tool to add a little contrast. Last I used an unsharpen mask to slightly sharpen the foreground area.
