I think #2 is good, but now that I look at it a bit more, I think I'd crop up from the bottom to get rid of the dead spot with the gravel. Shuffling it up and down on the screen it looks great with the left rail on the right side coming out exactly at the corner. I think it'd help pull your horizon down from being so close to the middle.
I hope you don't mind the subjective comments, but I don't have much else to do right now. Nice shots regardless.
