This one is particularly attractive, with it's "burning" but cold white light. Makes me feel like I do on a bright, cold winter day at the ruins, right before the weather changes for the worse.
(Is it winter, or is it really a summer pic?)
I think the B+Ws are very nice and technical knockouts, but I'm still mad for color.
I do like the way you're handling the monochromes, very individual style.
