Well I've noticed that most of users who reply in photography topic, tend to praise most of the photos. Well I've the lucky change to be a bad guy and be critical

I think your best shot is the 2'nd one... But lets start from photo no.1. You should really desaturater the eyes, they are too colorful for the rest of the photo. And maybe there is a little too much of empty room on the left side.
Photo no.2 good shot! Good concept. Just 2 recomendations, try it also in sepia toning, little more yellow, too much of orange atm. And try making nearly the same shot by playing more with the thirds. For example the shore (let call it shore) splits the picture into half. There is this light-house kind a thing in the bottom of shore... Try putting this on the left lower third and make the shore to run form that point to upper right point. These were just two wild-shot ideas I had, while looking t this. Although, you horizon is a little tilted. And maybe it would look better while all the corners would be darker... As the bottom left and upper right are.
Photo no.3 is totaly out of contoll... Your model seems to be leaving the picture, she is way too near to the edge. And what makes this photo even worse is the strongly tilted horizon. Fact that the chimney of the ship is out of the photo is also bad.... Well to bo honest, this photo wouldn't look that bad, if there wasnõt no person on it....
I hope you won't have any hard feelings after reading this!
