As the light conditions were quite poor the photos taken at ISO 100 are very dark. The ones taken at ISO 2oo are better and more manageable whereas the ones at higher ISO (400 and 1600) are probably too bright and grainy, although the camera has made all sorts of allowances.

I used ISO bracketing on this last photo to demonstrate the difference
