Of these three, Photo 2 speaks to me the most, I like the combination of lines (in the boards) and a circle (the boards' arrangement here) ... and I agree with cherrymoose on cropping out that stick on the left - you might even consider making this a "fill-the-frame" crop with bits of the boards reach beyond the border of your photo on all sides, also left and top, since those on the right already do so. Yes. Play with contrasts and saturation ... or try out an all black&white for this one, too (assuming #3 is b&w?!).
