So you're loving the light, and the juxtapostion of the marina in all its parts with the wilderness behind. My sense is that the light isn't emphasized enough, and the marina is too dominant. It's such a powerful form, with all its hard lines and dark shadows, it can afford to be much smaller to give the background and the light more room to breathe.
I think shooting this quite a bit wider, or from further away, to render the marina a small to medium sized foreground element, you can still have that nice pier leading the eye. I'd look for echoed shapes in the hills against the roofline of the marina, there's some promising looking ridgelines back there, especially on the right. Letting the marina go down so dark was, I think, a solid choice given your goal/idea -- the detail in there doesn't matter, but having it so big in the frame makes it obnoxious when it's that dark.
