For me this ticks a number of boxes for Erotic Art.
1. It maintains mystery - you have kept her charms from our eyes and we want to see more. That is always a powerful and more alluring position than just exposing her.
Its also more respectful. She is beautiful, and your camera treats her accordingly.
2. Your model appears aroused; there is 1000 points right there.
3. She is dressed in a kinky, unrealistic fashion on the bed...scarf, shoes and ankle warmers...this woman has hurriedly undressed and waits impatiently for 'me' to join her. Fantasy Island !
4. The red background screams SEX.
I think its a fun image that invites the observer to a decadent fling of irresponsible passion...so I like it very much
