Oh, I wish that I had either opened up the aperture or slowed down the shutter speed before I walked into this scene. At ISO640, f/2.8 and 1/30s, it was still possible to get a better exposure by a few stops. The second after I made the shot, the moment was gone. At such times, I ask myself if I have the right tool. (Most of the time, I do think so). Oh, well, at least I nailed the focus.
