What I really like about the first one is the purposeful waiting stance of the man and his dog - you have captured it well. I also liked the fact that there was someone on the other side of the street that the man and his dog could be waiting for. I started asking myself why he was in this pose, then I twigged. As a result, I think the photo might be more mysterious and intriguing if you had not included the pedestrian light. Just my 2p.

Thanks Chrisa... it's good that you see stories behind the picture. I do the same thing and try to guess the motives and meanings of the actions and stances of the people I capture.
