C&C per req:
1. A good idea, but not the best execution IMO. As metnioned, the image is soft, and has a distinct yellow cast to it. The exposure is fine, but the composition leaves me cold. I'd like to see a long line of these, or perhaps a closer perspective, but this view just doesn't work for me too many distractions, and even though the background is very softly focused, it draws my eye away from the subject.
2. A nice scene, but with some exposure issues. Your camera's meter was 'tricked' by the bright clouds resulting in dark, underexposed rocks in the breakwater. You could either use a graduated ND filter to even out the exposure (best method) or take multiple images and merge as an HDR. As well, don't forget to level your images in post.
3. Nice composition. The lines coming from the LR corner and hte angle of the boat drawing your eye to the centre of the image are excellent. In this case you've got a bright foreground and dark mountains, so an inverted graduated ND would have helped, as would a polarizing filter to reduce the reflection from the water and the upperworks of the boat.
Just my $00.02 worth - your mileage may vary.
