In #1, I think either more of the window or none of it at all would have worked better.
I agree with you completely for #2, the slight little bit at the bottom is just enough to draw the eyes down, but doesn't seem to be part of the photograph as a whole.
I definitely wouldn't say #3 is a stupid photo, in fact, it's my favorite of the 3! Photographs that bring back memories are always the best ones for me, and I congratulate you on photographing something that most other people would pass up!
