I think the last one is my absolute favorite. It reminds me of my favorite movie (Silent Hill).
I love the first photo's sense of layers. There's a fore, middle and background- but they're not at the usual proportions in the frame. Because the foreground is so close and the middle ground is so far away, it really adds a lot more interest to the photo. That and I love the reflection on the driftwood.
I like the second photo, but I think it would be a stronger image if there was something else in the frame. It's lovely to look at but it just leaves me with the feeling that something is missing.
The fifth image is another favorite- I love that you captured the cows mirroring each other. Seriously, great job. =0)
