Chân Dung Cận Cảnh Gáy Trong Nắng Hoàng Hôn

Vertical 9:16, ultra-close-up photorealistic portrait of an outdoor back view shot in the evening. A fictional adult Japanese woman, looking [24–32 years old]. The frame captures only her left ear, the back of the head, a hair 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 lowered. The left ear is positioned toward the top left, nape in the center, left shoulder at the bottom left, with bright backlit negative space at the upper right. Hair is [dark brown almost black], tied in a loose chignon at the back of the head, secured with one thin black U-pin placed diagonally. The hairstyle is slightly undone with fine baby hairs and stray wisps along the neck and ears. A small single-pearl stud earring rests in the left ear. The skin of the neck and ear shows natural texture, pores, fine vellus hair, and a few small moles. Her outfit is a [white cotton blouse or thin shirt] visible only at the left shoulder, with the collar outside the frame. Strong golden hour backlighting comes from a low sun at the upper right rear, casting a thin golden rim light along the hair contour, ear edge, and right nape. Background consists of soft white and pale golden bokeh suggesting a riverside or seaside, with no text or buildings. Warm amber and soft gray palette. 85-105mm lens equivalent, f/1.8, shot slightly above eye level. Sharp focus on the nape hairs, ear, and hair bun, with smooth depth of field blur across the shoulder and background. Natural, non-explicit, candid tone. Exclude faces, frontal features, text, logos, watermarks, necklaces, extra pins, airbrushed skin, CGI appearance, or illustration styling.
