I like the second pic ... i think the sunset is really good. the ray of light fringing at the corner of the cloud.
actually i have a comment also i thought that if the picture was composed such that the sunset was the back ground and the lighthouse (or is that a tower somewhere on the right side) was the subject in silhouette.. wow i think it will be v nice.
I think for the 2nd pic, the foreground is a little messy; otherwise, it would make a great pic.
I like pic 4. I thought the OOF tree was well placed and adds to the overall mood of the pic.
Thanks for sharing
