I have always been a huge fan of desolate looking places. Whenever anyone gets to shoot a picture like this, I love it because I know I will probably never go there. So it lets me explore the world through the eyes of other people's lenses who can afford to make the trips to these locations throughout the world. As for the composition, I like it, working in thirds is nice. I like the incongruous nature of the long hallway with arches, and the wall in the front left of the image. I like the exposure, the lighting, assuming it's natural, was a great time of day to snap it. I like how there is a single piece of wood on the right...not sure why, but it's an interesting out of place set of lines and darkness in the overall symmetry and light. I like the warm tones of the chipping paint and light splashing off everything. It makes me think if I only walk a few feet forward, I'll be able to turn to my right looking out a window out onto a beach, or mountains, or something even more beautiful than this image.
Disclaimer: I am not an artist, nor a photographer. I'm just another internet yahoo. However, yes, I do like desolate-looking photos and I admire your work.
However, while you capture the a sense of depth in this picture there are two things I think could be improved upon.
The first is minor. The wooden plank to the right is distracting. If there were other random items in the photo, it wouldn't be, but because it is the only object in the photo other than the clean walls and banister, it just looks out of place and it distracts my eye from rolling down that long corridor.
The second is unfortunate. I feel the picture lacks a story and you missed an opportunity to give the viewer a choice: take the long walk down the hallway or descend the steps into the unknown? From this angle, one might miss that there are a set of steps.
Not only do you find these fantastic locations, your composition choices are striking and often poignant. I think that may actually be a banister, but it looks like a gate beside an almost endless hallway...which could be symbolic, but doesn't have to be. Love that.
