I really enjoy this shot. The sunbeams, the shadows, all very interesting and cool. But I agree that it just doesn't look like night... I think part of it, for me, at least, is the white balance. Any chance of a cooler edit, or maybe a B+W? You're probably swamped with wedding stuff, but I think this is a great image, and worth some time to tweak in post, if you have time to spare...
