I like the contrast of the ship and mountains, very striking. In terms of criticism, there is almost too much docking. The metal working to the right of the ship takes away from the photo as well as the docking that blocks the view of the bottom of the ship. Saying all that I do realize it would be extremely hard to clone all of that out and it would probably be difficult getting an angle that would reduce the dock. But that is the only thing I can find, well done!!

I like this one a lot!! Nice B&W conversion, nice tonal range. I would recommend cropping about 10% off the bottom just to pull the tops of those far mountains a little more below the center line, you know the 'ole 1/3's rule thingy... I tried the scroll bar crop test and it really does help balance things and pull your eye more to the boat.

Beamer's suggestion works, mine was going to be try a panoramic crop, but I really like this one

Yes, the tonal range here and the detail kept all the way to the far mountains does it for me. I agree that a crop of some of the foreground might benefit the overall composition.

Nicely composed. I would add little more drama to the sky. Also some action on water would add a lot. Nice though.
