I agree. I like the first best, but I also liked the look of the girl on the centre left in the second, although that is more from my memory of her than the actual shot itself.
Reminds me of a series of photographs that someone took of people on the rain with a hidden camera. I think it's quite an interesting idea to observe people this way, somewhere between art and surveillance.
Wonderful shots Rob. I agree with Hamish's, and your comment tough. The second needs a crop on the left I think to make it balance. Love the light and textures though.
