hmm..I want to focus on the horizon, giving me an eye level perspective rather than a grounds up perspective. Would be better had there been something interesting in the upper left corner.
I think this might have been a better photo as a more traditional shot (as opposed to shooting for this specific challenge) -- I like the roof as a framing element, but much of the elements at the bottom feel like they've been _just_ cropped out (whether or not they actually have)
Even though the angle of the photograph is up, it doesn't convey to me the impression that the camera was on or close to the ground. I know from some of my photos that it can be on the ground, and not look like it, but I think the final impression conveyed is what counts. Otherwise nice picture.
I like the juxtaposition of the power lines and roof in the foreground with the skyline. I do feel some additional cropping would have helped emphasise it.
This is an interesting photograph but I'm having trouble relating it to the challenge. it looks like the buildings in the distance are the subject of the photograph. If that's the case, I understand the challenge attempt. If the overhead canopy is the subject of the photo, I am missing out on this altogether. if the light posts are the subject, I would have been sure to not clip them off at the bottom of the photograph. I am a firm believer that all good photographs should have a definite subject. You don't want to leave your viewer wondering what he/she/it is supposed to be focusing on. Keep up the good work!
