Good subject, good angle (though I might have cropped a bit more off the bottom to "lose" the black that intrudes on the left bottom), and a really good B&W conversion (I just love the tones you've gotten with this).
I like the simplicity of the architecture. So many times, there's so much going on, it competes for attention. This is very direct, and commanding. I like it a lot. Great color variations with the bricks.
