#3 is the most interesting by far, i love the exposure. There is so much stuff going on in that picture, shadows, textures, lines, volume, space... you should really play around with that idea! I don't like the flare all over the place, but even if you can't get rid of it, it is still a great picture. Shooting reflections on a window, you can also try a polarizer and see what you get.
Thanks for all the responses everyone. Keep them coming! #3 is my favorite but i only shot a couple of frames i wish i would have tried a few more things. :thumbup:
