I like it, too. I love it!! Your treatment is so perfect to bring out that feeling even more. The tracks add so much to the story. The cloudy sky gave you perfect light and fits the mood so well. I wonder about burning down the top even more (with a bit of increased contrast) to add to the gloom.
Excellent image Kostas. I like the feel that the vegetation is growing out of the foreground building and the way the top of the window in the rear building shows that the roof is missing. The disused road and tracks make great leading lines. We have a local train station in much the same condition, but alas, the tracks are gone and there’s an active house in the background that ruins the feel. The lighting and sky in this image really add to the feel of the image. Well done.
