Great shot. Seems quite underrated. Although it's fine the way it is, I bet had you sharpened this a little more and boosted the contrast it would have scored better.
The light on her face reminds me of a painting. I think I might have cropped tighter to her face, even if that meant cropping out some of the hat. I'm not sure about the white background, but her face looks amazing.
Love this with her eyes..great blue going on. She's so sweet looking. I thing a tighter crop would of made this pop a bit more. More impact. All the best in the challenge.
