Great flowing movement! There is a lot of symmetry in the curve of her body. Also the symbolism of a flower-like a bud opening from the pants and shedding off the outer protective sheath to let the pedals out. The pants showing is good because one dose not if she is coming out of them or if she is going to pull them up. The reflection of the box camera in the mirror is like an inside joke.
Very beautiful! I love the pose, although with the pants partially down instead completely off it looks a little awkward. I would love to see this same pose with pants off and again with panties left in a similar position as the pants. Like I said the pose is perfect as is the photo. Excellent Shot!
Now that's a beautiful artistic nude! Very expressive and great pose! Beautiful! (If I may... my only critique would be with the lack of pubes. It always reminds me of porn somehow, and I wouldn't want this to spread to artistic nudes as if it's shameful or something...)
