I was drawn to the very first pic, by IdahoG36. (1) I appreciate a good B&W photo. (2) I also like the use of reflection in a photo, be it through the use of a mirror, a lake, metal or whatever. (3) It's not a subject you see all the time. (4) And being somewhat a coin collector, it reminds me of the cameo look you see on brilliant proof coins: the dark background and bright device. Oh, yeah, I voted for it.
Sevens is right, the pics are all great. Nice job all.
