Overexposed lights, like my Helicopter Spotlight shot, and noise. Night photography is very difficult. I found the Noise Ninja encorporated into Bibble Pro does quite well with the noise. I think this shot is well framed.
There are some interesting elements here, but this scene is way too busy. The brightness of those lights doesn't help much. Would it of been possible to move past those lights and focus on the church as the major element with that great sky as a backdrop?
