I like the first one. Good color and composition. Her face might be a tad too bright though. That's more of a personal taste thing though.#3 almost seems....too sharp...for a portrait...if that makes sense. The lighting is good. It's just that it seems so sharp that it accentuates the blemishes in the model's face.#5 I like too, except for the distracting line where the shadow ends in the background, because it goes from dark to blindingly white, and the line runs through the middle of her face.#6 is O.K. in my eyes. Maybe a bit more contrast if anything at all?#7 The highlights in her face are really blown out. It's also obvious that a flash was used for this portrait, and there's nothing wrong with that for fill flash. The only thing is that it has the potential to totally destroy the shadows in a photograph, and I think that is the case here. Yes, you can see her entire face when the flash is used, but in my opinion it makes it look unnatural, and it causes the hair to sheen and gives the appearance of looking oily. Her skin also has a yellow cast in this photograph.#8 Same at #7#9 I like the light in this one. Although you can tell that flash was used like in the previous photos, there are still shadows that follow the contours of her face very tastefully. And the backlighting from the sun is AWESOME. Very nice use of light. If I had to criticize one thing, it would be that she looks kind of uncomfortable.
