I like this composition. The colors are bit muted for my taste. Would like to see bluer sky and water. I'd be tempted to consider cropping the white building on the left and the point on the right, but I like the width the way you have it.
I guess I am a traditional kinda gal, I don't feel like your main subject is really the land (or sea in this case) Aside from that it could use a little more pop, with the clouds it has a overly gray feel to it. jmho
