Good use of light: it reveals the structure of the walls. The door creates depth and creates some suspense. Maybe a little more off-centre to add extra dynamism.
Subtle is the nr 13...
I would have printed a grade higher since it is little bit gray: highlight/whites are missing. Anyway, well done.
Lovely photo, good composition and great detail. The black within the door way gives the image balance against the mass of grey tones Also, having looked at it several times I never noticed the cat on the top step...so much for my poors of observation!
The cat makes the photograph. Too bad he or she wasn't lying a litle more to your right so that he/she would have been in the sunlight and more easily seen. A very nice photograph nonetheless.
