Character Expression Sheet Generation (Anime Style)

Create an expression variation sheet as a single image based on the character in the attached reference image.

Format:
- 2 rows x 3 columns grid (6 panels of the same size)
- Overall aspect ratio 3:2
- Background is pure white (#FFFFFF)
- Panel borders should be thin and subtle (light gray) is acceptable
- Place small numbers in the top left of each panel: "1. [expression 1]" "2. Happy" "3. Ecstatic" "4. Sad" "5. Angry" "6. Surprised" (Black, easy to read)

Common Conditions (Must be completely identical across all 6 panels):
- Hairstyle, hair color, eye color, face contour, clothing, accessories
- Face direction (front), bust-up angle, head size, position
- Lighting, shadow placement, coloring (anime-style soft shading)

Only the "expression" can be changed. Do not change the pose or angle.

Arrangement (Fixed order: Left -> Right, Upper -> Lower):
1 (Top Left): Neutral expression. Calm, relaxed face. Mouth closed.
2 (Top Center): Happy. Gentle smile. Soft eyes.
3 (Top Right): Ecstatic. Full smile. Mouth open laughing. Strong highlight in the pupils making them shine (excessive effects unnecessary).
4 (Bottom Left): Sad. Eyes well up. Downcast gaze. Corners of the mouth turn down.
5 (Bottom Center): Angry. Frowning eyebrows with wrinkles between them. Teeth clenched (or lips tightly sealed).
6 (Bottom Right): Surprised. Eyes wide open. Eyebrows raised. Mouth open.

Do Not Include:
- Background objects, text (other than numbers 1-6), effect lines, sweat marks, different outfits, different accessories
