Cover Opinions Wanted

I'm going to be launching the first of my "singles" collections next month (more details on what a "single" is will be revealed closer to the launch date) and am looking for opinions on the cover design.

Note that the images used are watermarked as these are still works-in-progress, and the text will need to be tweaked before I finalize the cover, but these do give a rough idea of what I'm going for. You can vote for your favorite in the poll below. Thanks!

Reading the excerpt of "A Desolation of Grass" may help your decision-making...
