which image is the best?

These past two days I created these three images. All very similar but with slight differences. I am unsure which digital image I prefer. I am still working on the title, something about earth, life and the history of one's mistakes or past that effects one's future. All three of these images are copy written by yours truly, Diane McGarel.

If interested more of my computer images can be seen at mcgarelgraphics.
