Wow! A picture with only four elements, and the composition is simplicity itself, yet this is very good. Here's what I count:
1. A lovely model with very nice legs 2. An enticing pose, demure and sensuous simultaneously 3. A marvelous texture to the stockings that anyone would love to feel with one's fingertips 4. A stunning color for the background. It's as if the wood has been painted with a coating of azurite,
i think what is most appealing is the contrast of textures -- wood, stockings and gown.
