Love, love, love them all. The first one is gloriously abstract, and they get so few B&W entries, which could be an advantage (you'll stand out) or a disadvantage (too abstract), depending on the judge. May I suggest you go back and read what the judge is looking for, and use that as your guide? (Hopefully the judge's statement will be clear -- sometimes it's not.)
