Japanese Manga Character Triptych AI Image Prompt

Create a triptych graphic poster on a vertical canvas divided into three horizontal panels, featuring the same Japanese manga-style character in every panel. Keep the face, eyes, nose, mouth, face shape, age, and hair color identical, changing only the hairstyle, bangs, expression, head angle, glasses, and accessories like a professional character design sheet. Each panel should be a shoulder-up portrait with bold graphic poster aesthetics, thick clean line art, minimal detail, and large flat color shapes. Choose three distinct moods inspired by the chat history, expressing each through a single dominant color with only black and white added. Instead of a traditional background, immerse the character within the atmosphere itself so the ambient color naturally reflects onto the skin, hair, and clothing, creating the feeling that the character exists inside the light and air of that world. No text, logos, UI elements, or speech bubbles. Each panel should work as a standalone artwork while forming a cohesive series together.
