Kundenstimmen-Karte mit echtem Nutzerfoto

Design a vertical 9:16 UGC-style social post featuring a real customer photo paired with a short testimonial quote card. Show a believable everyday user holding or using the product in a natural setting, with soft natural light, candid framing, and a phone-native look. Add a clean, readable review snippet and subtle brand-safe graphic treatment that feels like a reposted customer story rather than a polished studio ad. Keep the composition mobile-first, authentic, and slightly imperfect, with realistic skin texture, natural shadows, and casual styling. Use simple typography, minimal decoration, and strong visual hierarchy so the testimonial is easy to read on a phone screen. Negative constraints: no glossy studio lighting, no overdesigned ad layout, no fake-looking smiles, no heavy retouching, no cluttered background, no watermark, no visible platform UI, no distorted hands or text.
