You did awesome!
I love shooting Disney on Ice and hate that it's such a game to even get a camera in there in the first place. I'm curious, did you have you daugter carry it in? Did they say anything about it?
I'm guessing the overexposed photos are the result of the metering mode your camera was set on. I mentioned that at one point. If you use evaluative metering (where the camera considers the light in the entire scene) it sees all that black and tries to boost the exposure, leaving the subject of your scene overexposed.
If you use center weighted or spot metering, the camera considers a much smaller section of the scene to see what exposure to set. For spot, it's very small, for center-weighted, it's a little bigger segment. I think changing to one of those would have made the difference.
But overall, a great collection of shots!
