半身低多边形肖像插画

From the uploaded portrait photo, transform the person into a half-body low-poly illustration. Keep their recognizable face, shoulder-length hair, and neutral expression. Style: sharp geometric triangular facets, soft polygonal shading, clean shapes with realistic proportions. Clothing: simple pastel top based on original photo colors. Background: soft gradient from white to beige. No outlines, no text, soft lighting. Minimalist and stunning. Aspect ratio: 3:4.
