Generally increasing contrast and sharpening work for starters. See if that meets your expectations.

With a mask slightly darken the back ground (water and sky). Maybe in curves...many ways to do it. Be careful to not over do it.

I would put some blue in the sky, darken the background consistent with sunset, and apply a warming filter to the foreground for a sunset effect. Something like this:

a wee bit of tilt to the right wouldn't hurt. Won't make it pop, but will straighten it.

Unsharp mask 50 pixel radius 10-15% is a good quick start. Agree with the blue background, contrasting warmer foreground colors with a cool blue background is widely used.

I think the original is quite nice. The re-work has more tonal separation, but is not as appealing to me.
I'd cautiously bump the contrast in the original, perhaps selectively darken the water. But use a gentle touch.

This is one of those that I found to easier working in Lab. Steepen the curve in the a & b channels. Add a bit of clarifying USM @ 40/20/0, then fiddle with some selective color or H&S in layers as needed. The old standby of burning down the corners may also help. I posted two quickly made examples. Or leave as is for a misty flarey soft seaside look. You are the artist!
(Hope you don't mind I did the work and reposted them. Original is on top)

Really nice reworks!
I'd vote for something in between the first and second rework above (second is a bit too warm IMHO). Both really do a nice job of adding that pop I think you are looking for.

A lot of the stuff I do as a layer with a layer mask so I can add, and or mask off as needed. I agree, these are a bit rough.

Thanks for all of the suggestions. I have worked with the contrast and also applied USM of 50 with a radius of 10%. I did level the horizon a smidge and am quite happy with the results.
