Thanks for the comments everybody. Samsam, maybe next time try to get in a little closer to the action in the first photo, to show the two men in opposite directions a little more predominately. Of course, it's not like you can redo it, so critiqueing is a little less appropriate I think.
I personally take quite a lot of very close pictures and most of them I throw out because I think that they aren't very interesting so Samsam, take my advice with a grain of salt. Occasionally I'll get one in close where the central figure is juxtaposed with another that really makes things come together (like my first photo) which I feel is a sort of contrast between new and old. Unfortunately in the small web jpeg, you can't see that there is a man on the other side of the street looking directly into my lens as well (you can't see his face unless your looking at a 16x24 enlargment). It bother's me the young guy isn't in sharp focus, but I've had several art lovers say that this adds to the dramatic differences shown between youth and old age, but what do they know? The second one someone was swinging an umbrella at me, possibly to prevent me taking the picture. Not sure if they thought I was taking a picture of the baby or not.
Pixtu, I like the picture you posted as well, Winter beside the sea. At first glance I wish there was a little more shadow detail in the wall (or the dark part of the photo between the shoes and the knees). However, I'm not sure that wouldn't alter the mood of the photo, which is really great. I like the motion and the sharpness really doesn't bother, actually I enjoy that it's not sharp, adds to the air of the photo.
