Nice composition with its balanced lines, converging rails and sharpness of detail throughout. OK, here's my attempt at an artistic interpretation: The color choice seems to create tension with the sharpness by not allowing the door and the nearby brick to achieve their potential clarity. So, on the one hand we have an obvious pathway drawing us up toward the door, on the other a door which is just beyond comprehension. If that was the intent of the post-processing, congratulations! If not, know that these words come from a totally untrained critic. ;-)
