Nice harmony all along in this one, though I dont usually like motion lines from walking people, the stable and well thought background offsets it and makes the idea viable.
The motion blur gives me the impression of hectic city street, contrasting the reletive serenity of the cafe. The whites are just a little blown for my taste.
Great contrast on this one. The most clear part is the building door in the background, but I think the subject fails me. Because of the out of focus people, which is where my eye naturally goes first, the composition seems reversed. Perhaps a better way to do it would have been to pan on one particular person, blurring everything around him? Don't know, but I did an experiment where I panned my hand with the camera to blur out the background, and it really came out good. Try it yourself. You'ld be surprised how detailed you can get when moving your camera at the same rate of speed as the subject.
Very nice. I really like this shot personaly! the slightly laged shutter makes a wonderful effect along with the architectural detail! i expect you'll get a high position in this challenge!
