This is the first of a number of 24 locations I have to photograph around New Zealand over the summer for a client of mine.
Nikon D800E and Nikon 14-24mm G lens
Since some others have offered critiques, I will try my hand as well. I agree with some others about colors the exterior lighting. Personally, I would prefer less of a purplish bias to the exterior. This is not to say that a purplish cast is wrong for twilights, just that it seems a bit strong to me for this particular shot, with the lighting at hand.
As to the color of the interior light, which some have said is too yellow, I think maybe in this case it is too warm, and perhaps could be biased a bit more orange and less yellow. For a later, twilight, shot, I think it might be a different case. However, the colors for these kinds of shots can be rather subjective and don't necessarily have to be strictly what the eye would see in real life.
Also, I think this could have been shot later, which would have yielded a more dramatic effect (assuming that would be acceptable for the client). And, while I like the composition, I wonder what this would have looked like shot from a little further away. As it is, I find the scale (near-far) distortion a bit strong for something like this. However, maybe there wasn't enough room for other options?
Lastly, I would have added some light to those skylights on the left and maybe lightened up the upper windows to make them closer in brightness to the lower ones.
