never, ever clean your windows. there's a magical world that lies just outside your windows that might disappear if you clean them. you don't want to take that chance, do you? ;)
this is absolutely stunning ... boysetsfire asked me if i'd got some b&w advice from you, but at the time i was unaware of your talent and hadnt seen your work before .. i've just had a look in your portfolio and i now know why he asked, coz it appears you have an amazing gift for b&w & i love your creative approach with your photography ...
This is a great shot, interesting lighting, looks like it was directly overhead but you also look to have some from down and to the left. Not sure if I can tell exactly.
I've always found window reflections fascinating to photograph and difficult to do well. You've excelled with this one. (I only wish the inverted double "U" shapes had been cloned out because they compete for my eye's attention.) Superb capture of the child's face and the birdhouse in the background. Well done.
