Vibrant Watercolor Portrait Creation

Create a vibrant and artistic watercolor painting of a smiling person, using the uploaded photo as the facial reference without altering their facial features or appearance. The background is clean white, filled with dynamic and expressive watercolor paint splashes in {argument name="splash colors" default="blue, orange, and purple"} spreading organically across the scene. In the foreground, a realistic human hand holds a paintbrush as if actively painting the sleeve of the man's hoodie, creating the illusion that the portrait is being painted at that exact moment. The visual style combines detailed ink line art with loose watercolor textures, including paint drips, fine splatters, soft pigment diffusion, watercolor blooming effects, and natural paper texture. The image features strong contrast, an expressive and dynamic artistic look, a clear hand-painted aesthetic, centered composition, soft lighting, high level of detail, and a modern illustration style.
