The Vespertine vs. Dark Angel vs. Forgiven
Now, I know the first two are the same image, and while I'm pretty sure the last one is from the same photoshoot, I still have some doubts. I'm really only going off the dress, here. It looks the same to me, but I could be wrong.
Anyway. I don't really like any of them. First off, why is she running in a dress? It just doesn't make sense. Running in a dress is hard. If I had to pick one, it would probably be Forgiven (which took me forever to find, because I thought it was called Forsaken and couldn't remember the author's name). It just looks a little better: the color of the dress, her hair, the angle, what you can see of the model's expression. In the other image, the model looks to be making a sort of weird face. Vespertine's dress color is too blegh, and Dark Angel's is too RED. I also don't like the swoopy, feather(?) thing on Dark Angel.
