Skunk and possum photos like this and the one below are getting better, I think. I have refined my technique for taking flash photos at night through glass. By placing some opaque surface flush with the glass and above the lens, most of the reflected glare from the window misses the lens. The flash does reflect a good deal off the glass which blinds me for a moment if I forget to close my eyes when I trip the shutter. The larger problem is there really is not enough light for accurate manual focus.
