Congrats! Wonderful photo. Had my vote.
Any more background on this? Where? Technical or other photographic challenges is taking it?
Clarification please - Cats AT windows - as seen through the glass or can the cat be in front of the glass (either interior or exterior)?
This photo had my vote from the start. Absolutely wonderful light and composition. Did you scope this out beforehand and wait for the light or was it one of those moments that you happened to be there - right time, right place and prepared?
Sorry, but putting a red filter over the entire image does not meet IMHO the intent of the contest. Interesting effect nonetheless.
