Camera Work/Technical: I like your choice of settings that yielded every element in crisp focus, as well as the tones and colors that you captured. I also like the long exposure that you used to make the Christmas lights flare into stars.
Lighting: Also very nice. Your use of the Christmas lights provides a very warm, inviting feel to the image.
Composition/Content: Also very strong, in my opinion. I really like how the window sill draws the eye into the image and the boots, Christmas lights and city lights hold it and keep it moving.
My Opinion: I think you really stretched this one to meet the challenge, as did most of the voters. When I'm going through voting, I rarely look at the image titles. Rather, I rely on the content of the frame to meet the challenge. I have been hammered on this at times myself, so I fully understand. I think that it is a strong image, but it just doesn't fit into the challenge.
I think the idea of the suction cups is cool. Unfortunately its hard to really get that from this picture (it took me a moment to realize how the lights were attached to the window). I am also not really sure what the boot has to do with the challenge.
Although there is something sticky in this image (the suction cups), I don't feel the image is 'about' sticky, and the boot just doesn't make sense visually in the picture.... sorry.
