Ishmael,
I like four of them:
#2 made me smile: where's the other foot???
#3 is just brilliant. I'm not sure about the poignancy (you have to know where the photo was taken, which isn't obvious, you have to make assumptions about the biker, which aren't necessarily correct) but the effect of seeing a Chinese (or is he Tibetan) James Dean gives a jolt to me and brings a second and a third look.
#4 is, for me, the best of the lot. Now that is poignant, and the shot is excellent because it requires no explanation.
#5 vies with #4 for the best shot. What makes it fly for me is the juxtaposition of the prayer-wheel and the money in his hands, and the fact that the viewer is looking up at the old man, making him look imposing and rather threatening. Shame about the white sky, but the shot is good enough for you to get away with this.
#1 is technically good but, for me, forgettable.
Thanks so much for sharing these - I think they are great.
Ed
