The image is definately improved by the sepia effect- which is a very good use of that filter. I really love the textures captured: sky, gravel, railings, and grass. One can't help wondering- where will this road take me? Adding this to my fav's.
We have a few marsh walks like this around here. I like the zig-zag in the distance. The sepia helps you focus on all the linear elements and great textures.
I love that "old" feeling of weathered wood here...I just wish the sky had not been quite so white. We have that kind of a sky here in Oregon a lot too. But its nature and it doesnt alter the beauty of this photo..
