My vote goes to “Haiku for the Ox.” It’s short but has a motion to it and the implicit image of turning over soil works well for the piece.

As for the others, I enjoy the strong language in “The Pride of the Ox,” especially the energetic line, “Jugular spilt a spew.” I do think, however, that the line is perhaps a little short in a way that can hurt comprehension and not leave enough room for the words to really breathe as much as they deserve to. In regards to “Dew,” I like the whimsy but I think that it would have been improved by seeing a little more of the grass growing wild before being eaten.
