I really like the first one better. Not only the composition, but I don't ever remember seeing so much detail in a night shot without completely washing out the highlights.
What camera settings did you use, and you did use a tripod, yes? Or did you really "just snap it"?
a very nice work. Both of them. The first one has a gothic touch, close to Comic-like illustrations (at least the whole left front of buildings, awesome). The second one, as well stated by other replies, with that singular touch of the diagonal lines.
