I like the composition. I like how the straight lines and angles on the left juxtapose with the curves on the right. It would be interesting to compare a color version to this photo, but I would say the B&W keeps the viewer focused on the lines and curves. Nice image.
If this weren't so cool it'd be funny. It really does look a bit futuristic, and with that sign, it could be a bit intimidating. Love the way you composed and processed this. Just a hint of people makes it.
Like the shapes. Does draw my eyes to too many places in the photo though. I don't know were to look? Love the grainy look in it though. Compliments the black and gray nicely.
