Well you have some attractive models willing to help so don't waste it. How do you rate these? What do you like/dislike? what kind of style are your looking for?
2nd one is really good, first one the white pulls your eye toward it... I'd photoshop the hair out of her face and keep an eye on their necklaces easy way to ruin a shot if they feel comfortable taking them off it's probably better.
nice.. both would have been better if you hadn't cut the top of her head off. Portrait orientation would have allowed more subject and less junk (although #2 is forgivable!)
