In this scenario, you have a very clear devision between the foreground and background, you could take two exposures. Put your camera on spot metering, take on exposing the foreground, and one the sky. Of the two you'll then get the perfect exposure of both and you can merge them in photoshop. This is something I have been doing with landscape work. Although I have yet to post process them, I often take two exposures or more so that the sky doesn't burn out in low light etc.
The sky does look a bit off on this, like you say probably a white balance confusion with tugsten vs dusk etc.
Nice selection of images, you've obviously put alot of time and consideration in to this project and it shows. Nice work.
Thanks for the feedback, Nick. Of all the images in my gallery, I also think that the colours in this particular one are not quite right. This problem usually occurs in situations of mixed lighting, such as that shown above. While the courtyard was being lit by the tungsten bulbs, the sky still had a cool light left in it. This is one of the first images in my Cambridge gallery with my original Canon G3 camera. I will repost a new version of it before long with a more accurate white balance...
great composition and exposure. Colour looks a little surreal to me... Very warm for what looks like an early evening exposure, have you made adjustments in PS?
