带遮挡效果的波波头电影感肖像

Create a photorealistic close-up portrait of {argument name="subject" default="a young East Asian woman"} with a short chin-length black bob haircut and soft natural skin tones, framed from the upper chest upward in a vertical 4:5 composition. She wears a black pleated textured blouse with a subtle ruffled neckline, photographed in dim soft indoor light with shallow depth of field and a blurred neutral beige-gray background. Use cinematic realism, natural shadows, muted colors, gentle contrast, fine hair detail, and a moody intimate editorial style. Add the word {argument name="watermark text" default="Alconia"} in bold light gray sans-serif lettering at the bottom left like a watermark.
