Cinematic Backlit Nape Portrait

Vertical 9:16, ultra-close-up photorealistic portrait of a back view shot outdoors in the evening. A fictional adult Japanese woman, looking age. The frame includes only the left ear, back of the head, hair in a bun, neck, nape, and left shoulder prominently, with eyes, nose, and mouth completely out of frame. The head is tilted slightly to the left, chin slightly lowered. The ear is positioned towards the top left, the nape in the center, the shoulder at the bottom left, with bright backlit negative space at the top right. Hair is hair_color. Tied in a loose chignon at the back of the head, with one thin black U-pin visible diagonally. The surface is not too neat, leaving many fine baby hairs and short stray hairs around the neck and ears. A small single-pearl stud earring in the left ear. The skin of the neck and ear shows pores, fine hairs, and a few small natural moles. The outfit is a outfit visible only on the left shoulder, collar out of frame. Strong golden hour backlighting from a low sun at the top right rear. Thin golden rim light on the hair outline, ear edge, and right side of the neck. The background is a large white to light golden bokeh suggesting a seaside or riverside, with no identifiable buildings or text. Overall tones are warm amber and soft gray. 85-105mm equivalent, f/1.8, slightly above eye level. Precise focus on the nape hairs, ear, and hair knot, with a smooth blur on the shoulder and background. Skin looks natural, not sensual or explicit. Exclude faces, eyes, mouths, text, logos, watermarks, necklaces, multiple pins, extra ears, distorted necks, unnatural hair like shaving marks, excessive skin smoothing, excessive flare, nudity, underwear, illustration feel, or CG feel.
