You sure have some interesting places to photograph. My favorite is the fence on the beach. Sure, it's a photographic cliche, but one that's enjoyable to make when you encounter a fence in the sand or snow. Your beach/wave photo is nice, too. Nice "moment" to snap the wave.
I have to agree with the others and say that the fence on the beach is the best one.
The beach landscape is nice too but I think the sand could be a little better exposed... seems just too dark but when you got the sun in the composition thats going to be the dominant light source...
i like the 1st of the ones on the beach (towards the end) with the footprints going away and the sea is retreating. i like the rays coming through the clouds.
