Spooky! I particularly like the subtle glints in the background, they add mystery. Although one of them makes her look like she has a horn (normally not good!), here it is oddly appropriate.
Well done portrait. The very shadowy low key treatment really works well for this image. A few distracting background items are all that keep this from being perfect.
Good image. Enough light to see enought to keep it interesting and dark enough to keep the mystery. Looks more like a painting than a photo. I don't feel that this was the spirit of the challenge, but it's still a good image.
8. Too pretty to be seductive. My preference would be for another option regarding the necklace. Black glass cross with a smaller smile would be very provacative. Beautiful model. Excellant skin tone.
