4. Aspect ratio: Vertical format, subject slightly left of center, eyes positioned near the upper third line

II. Facial Features and Expression

2. Eye features: Large eye proportion, clear eyelashes, gaze focused on the lens, slight under-eye bags and soft shadows

3. Lip features: Full and moist, soft edges, with distinct highlights and a jelly-like texture

4. Skin texture: Extremely smooth and refined, minimized pores, overall fair and translucent

III. Makeup Style

1. Base makeup: Combination of high coverage and soft matte finish, with natural highlights preserved in certain areas

2. Blush: Pink blush diffused from cheekbones to under the eyes, light but visible

3. Eye makeup: Fine upper eyeliner and natural deepening of the outer corners, light brown-gray gradient, overall clean look

4. Lip makeup: Gradient from pink-beige to light rose, layered with strong glossy effect

IV. Hairstyle and Accessories

4. Earrings: Small studs positioned on the earlobes, understated accents

V. Clothing and Skin Details

1. Clothing: Red thin straps, backless design, straps clearly visible on the right side of the frame

2. Skin glow: Soft reflections on the shoulders and back, presenting a delicate creamy skin texture

VI. Lighting and Tone

1. Main light direction: Soft light from the upper left front, wide coverage, very soft shadows

2. Fill light: Weak fill light from the front, reducing contrast, resulting in almost no hard shadows on the face

3. Highlight control: Small-area bright highlights on the bridge of the nose, upper lip, lower lip, and edges of the glasses

4. Overall tone: Low contrast, soft matte feel, subtle gradations, dark areas not overly black

VII. Background and Environment

2. Depth of field: Strongly blurred background or inherently minimalist, making the subject's silhouette stand out

3. Atmosphere: Clean, tranquil, with a slight sweet-cool feel

VIII. Lens and Image Texture Simulation

1. Focal length feel: Medium to long telephoto close-up compression, natural facial proportions without exaggeration

2. Depth of field performance: Eyes in sharp focus, ears and background noticeably blurred

3. Sharpness: Facial features clearly defined but not overly sharp, overall soft appearance

4. Noise: Almost no grain, presenting a clean commercial portrait texture

IX. Post-Processing Key Points

1. Skin smoothing: Strong but natural, preserving some facial structure and shadow transitions

2. Color: Overall cool, fair skin tone; blush and lip color leaning pink; red straps saturated but not excessive

3. Glow: Slight soft light diffusion effect, making highlights more rounded

4. Consistency: Control contrast and sharpness to maintain a transparent, soft, and clean visual consistency

X. Negative Prompt Words

2. Character issues: Exaggerated expressions, wide-open-mouth smiles, rough skin with visible pores, oily shine, facial distortion

3. Style deviations: Heavy stage makeup, strong retro color casts, complex clothing, exaggerated accessories, strong environmental light interference
