I like what you did with the crop on the first one, and I think it is a very nice photo. It is what I picture when I think about New England ports and bays and such. I love looking at these coastal types of photos because it is something I never get to see living in Kansas.
There is nothing wrong with the second and some may really like it but the subject matter does not do much for me.
As for the last one, I have to agree with the others, it is a stunning shot. And I can't believe you got those bird in there also. They are in the most perfect spot in the frame too (how lucky), they really add alot. I don't agree with the others that say it is oversharpened. I think it is nice you can see so much detail in the rocks and such.
and one more thing- I'm trying to figure out how the rocks facing away from the sun got lit up (I figured they would be in a little more shadow), or are they facing away from the sun? I can't really tell.What ever you did works
