The second is most interesting to me, particularly in the abstract content. I don't get the framing of the other two in the same way as I get the second - ie I'm finding it harder to connect with why you felt those were the right places for the edges of the frame to be. Did you consider alternatives?
I don't think that 'abstract' breaks the rules of photography because it is an inherent property of every image, whether conscious or not. Photography does what you are trying to do here very well, I believe.
