保留身份的 3D 水彩肖像

Use the uploaded reference image to **preserve 100% of the facial features, identity, age, skin tone, and expression** of the person. Create a **3D watercolor-style portrait**, blending a softly sculpted semi-realistic form with delicate watercolor textures, pigment diffusion, and soft painterly washes. The person retains exact hair, skin, and expression from the reference. Clothing: casual or neutral outfit ({argument name="outfit type" default="shirt, coat, or reference-inspired"}), rendered with layered watercolor textures and subtle 3D depth. Pose: natural and relaxed, sitting, standing, or casual hand placement. Background: soft watercolor environment, outdoor or indoor, abstract or lightly detailed, with gentle gradients, flowing textures, and subtle atmospheric depth. Soft lighting with gentle highlights and blended shadows. Highly detailed face and upper body, masterpiece quality, cinematic painterly composition.
