The clouds generate a moody atmosphere I like, so no need to wait for better light. I would crop the bottom a little bit (near the shore; if you want to keep the aspect ratio you can crop from the left too, but that's not necessary in my opinion)
You might try to raise the shadows in the lower half of the picture in post, but other than that I like the processing too.
With the next two points I am beeing picky and if you don't remake the picture forget them, because your image is good as it is.
The sunspots in the trees are somewhat distracting for me, if you have those weather conditions again wait for a moment those spots are gone, or maybe they fade when you raise the swadows a tad in post.
I don't like that the first ship in the background has reached the treeline already, one minute earlier and both ships would have been wholly in the ocean, as I said I am beeing picky now
