I love how you set things in order to highlight the softness of your model's skin, and the watercolor feeling of the light areas combined with the white background.
The deliberated diagonal inclination makes it so obviously comfortable for the eye, but despite the fact that you use this often, i think the beauty of this one goes far beyond, no matter if you used a formula more than once.
It is cool how you repeatedly use black and white for the rest of the elements and let the women beauty be the only owner of the colors. There's something odd about the focus, i would prefer more focus on the right (near) hand than in the left (distant) hand, or maybe focus on both... but, yet this is not necessarily relevant...
Not to be repetitive... Just a comment about the angle.. Hitting the bottom left corner almost precisely, locks the image where it should have been dynamically un intended... 5 degrees ccw and moving away from that corner, as to afford the brain to visualize the details beyond the frame... Would have complemented this heavenly beauty better. All the good points are covered already by the other commentators... I love your work, it makes me happy.
Pose and expression - she looks authoritative - like the owner of a fashion studio, directing her models and staff while changing outfits herself. She's very calm and self-possessed; very good at what she does. .... just my wild-ass guess, of course - what's your take on her?
