The black background really emphasises the colour in the makeup. The lighting aids the contour of the face and adds to what the makeup already started.

The lighter background works well on more natural makeup where highlight and strobing is more of the emphasis than contour. I also like having one eye as the focal point with the other either hidden by hair, shadow, or just cut out of the shot.

What I like about these photos is that even though the eyes are mostly the focal point, there are other things going on in the pictures. I'm extremely drawn to the photo on the bottom right, where the hair is covering her face. I would me more inclined to make the eye stand out just a little bit more though, maybe with makeup or just using a model with a more striking eye.

Ward's style is very dark and not usually what I'd like, but I think it captures eyes in a really different way than the others. Maybe this is something to do with the masculine models.
