I tried to find a reason to give this a 9...
But I couldn't bring myself to do it. This is just too cool. This is what impressionism is all about... it's very evocative and atmospheric, as others have said. The only changes I could possibly suggest are entirely personal preference, so it wouldn't be fair to dock you on that. That being said, this already awesome piece could possibly be more appealing to me personally if the following were done:
-Slightly wider color pallet. The sepia-tone-ish look is cool in its own right, almost reminds me of Korriban from KOTOR 1, but this seems almost hopeful and warrants subtle addition of hues to the sky, the ships, and perhaps the monks.
-Speaking of which, the monks could stand out more, either by adding subtle coloring, or making them more exposed or maybe standing in a beam of sunlight filtering through holes in the overhanging wrecks.
-Texture. This is damn good, and I would guess excruciating realism is not your goal anyways. But, adding texture to the rocks and ruins and ships would make the give the picture depth and make it pop-out a little more.
If you decide to update this later, I would be eager to see it, whether or not you take my very subjective advice.
