For this one, I believe you were right and the voters were wrong: for the most part. I believed that this photo was way more 'Color Studio Portrait' then many of the photos that scored higher. Yes, they may have been better photos but I didn't see them as something somebody would do in a studio nor as a true portrait. Your lighting is a little bright but I think you got 'Studio Portrait' over many of the other photos. Keep up the great work and it's good to see your still at it!
Cute model, but very harsh on camera flash combined with her putting her weight on her hands take away from the photo. The flash causes the harsh lighting and the hard shadow behind her. She does not look very comfortable having the photo taken.
Great attempt, and you certainly have a good model to practice with. Keep at it.
Some rather harsh shadows in this shot. Bring your subject away from the back ground and use a defuser to soften the light. It also looks like the flash was fired on camera. If possible, it would help to get the flash off camera.
