I think I like the last but one best of all, the sky is really nice in that one and the colours come out well.
The sky in #1 to too bland, blown out, really, while others are a bit too dark ... and what has brought about the heavy vignetting in the last, I wonder?
The last one I vignetted post production manually in PS. The sunset wasn't that good, I agree with tsar, but I wanted to go take some shots, the focus being on abnormal angles and composistion. All of these photos were taken with manual exposures and settings. Certain pictures I tried different things, hence the reason why the house with the street number is taken twice with two different exposures and apertures.
The only other post editting I did was with the first one where I threw a sharpen mask on it because it looked a bit blurrier than I wanted.
