Photorealistic boudoir portrait of a fictional adult woman, 27 years old, sleek black hair in a low ponytail, warm olive skin, defined brows, sculpted cheekbones and a composed knowing gaze, wearing deep-plum satin corset with wine-red lace trim and an open black silk robe over her shoulders, leaning on a dark slate table with a large open book of completely blank cream pages resting on it, the pages entirely empty with no drawings, no maps, no lines and no marks of any kind, and plain brass dividers beside it, warm ochre light, no text anywhere, elegant sensual atmosphere, soft cinematic light, tall portrait composition, high detail
