Studio Portrait with Red Gradient Background Prompt for Nano Banana Pro

Turn my uploaded image into a clean studio-style portrait with a deep red gradient background and soft vertical panel textures. The subject is wearing a {argument name="jacket color" default="maroon"} oversized puffer jacket, a festive patterned sweater, and a cap with glasses, holding a large red-and-white candy cane. Use soft cinematic lighting, sharp focus, vibrant colors, and a polished commercial photography look. No text, no logos, no UI elements.
