something bothered me about these portraits and I was having a problem figuring out what it is. I'm sure it's the woman's hair. I want to go get the hair out of her eyes, or at least arrange the wild hair tangle so it's more pleasing to the eye. that's it.
These are all wonderful. Not just for the tonal qualities, light, etc, but because they show the passion of the dance. A credit to both you and your models/teachers. A nice reminder that there is beauty in the world - exquisite and joyful.
