Wonder if any of you guys can give me any tips with the following please. I took two long exposures recently of different cities. The first one I'm happy with - the buildings are relatively sharp, there's some nice light features, and there's reasonable detail.

P1010863 by Ben Taylor, on Flickr My question really then is how could I have made the second one as good as the first? Or at least better. There's loads of differences but not sure which of them it is that made one obviously a better shot. Most factual details you can glean from flickr, only facts I don't think you can glean are: Direction - first (good) one was facing approx south east and second (bad) one was facing approx east edit: west. First (good) one camera was resting on a wall. Second (bad) one camera was on a tripod (velbon sherpa). Time - relatively same - first (good) one about 7:05pm, second (bad) one about 7:15pm, so after sunset but not much. The first (good) one I think I could have forgotten to focus entirely, I was preoccupied with setting it up steady (BBF , but also focus priority is on...?) The second (bad) one was manual focussed to infinity.
