Hi,
I like 2 and 4 the best, and maybe 1. It all depends on what the person is looking for. Art is subjective you know. The blown out hilights are a bit distracting on most of them. On #4, I would fix watever that is at the front of the image to minimize distractions. #1 would be so much better if it were not for the blown out parts of the foliage.
I like the geometric shapes and lines in #2--my favorite!
