[Subject Specifications] A beautiful and very attractive Korean college freshman woman, early twenties. Lithe hourglass silhouette. High-fashion white supermodel aesthetic. Subject is exiting the doorway, stepping forward into the dark expanse. [Lighting & Physics Engine] A dance of light and shadow. Volumetric god rays in a full rainbow spectrum. Source unseen, filling the dark expanse. Physics: God rays are drawn toward the portal doorway, not emanating from it. Many different colors of light fill the doorway. Light highlights parts of the subject while leaving others in deep shadow. [Texture & Material Properties] Gown billows out around the subject, flowing longer than physically possible. Fabric captures and absorbs individual god rays of light across different parts of the skirt. Crystalline dust particles suspended in the air.
