Ricardo. Although the out of focus aspect does create a mood - it is not out of focus enough for it not to be acknowleged as poor technique and a bit uncomfortable to look at. Even really out of fous images are really difficult to get to work. (threads in the past few months ) In saying that- if you like it anyway, I think that's the most important thing.
I also agreee with russell a, that the green of the brambles seems to destroy the graphic element of the wire. I would not however agree to burn it down - unless you own the property- we call that arson over here. I would have liked to have a play with the Channel mixer, but your image is so small that I was not able to.
I would go to the site in the day time, and explore the composition of your images in daylight. Take a notebook or sketch book, and get a feel for the composition and structure of the images which inspire you. Then let the night-time exposure and light assist the mood - and create unseen suprises with the different light and shadows.
