I like it alot! Good ideas with the colors. The picture is very small though, you don't have a larger version?
Something even kooler than this would be if that plant thingy on the bridge also were in grayscale! I also like that the trees are creating like a border around the picture, also very kewlz0r.
I think that text looks more like some design thingy. The text isn't the thing you should concentrate on in this picture. It should be small and not drag the viewer's attention towards itself.
Good job on this!
