Visual Kỷ Niệm Nhóm Idol Bốn Thành Viên

A clean Japanese anime idol anniversary key visual featuring a four-member school idol unit in a symmetrical stage formation, square 1:1 composition. Setting & Background: Soft cream studio background. Oversized, flat, pale pastel typography sits behind the characters: "[Liella!]" rendered in light pink across the top, and "[2nd]" in soft lavender-blue behind the center, both partially obscured by the figures. Characters & Poses: Exactly four teenage anime idol girls in coordinated color-coded plaid stage costumes with white puff sleeves, layered frilled skirts, neckties, colored wristbands, white socks, and white stage sneakers. Their overlapping pleated skirts form a star-like silhouette. - Front-center: [red-haired anime idol girl] with bright red twin-tails, blue eyes, and a confident smile, kneeling low with hands on the floor. Wears a pink-and-red plaid vest, pink skirt, and magenta tie. Her face is completely clear and unblurred. - Left: idol with long [blue] hair, blue plaid outfit, and blue skirt, in a wide side-lunge pose with arms extended forward in a rounded gesture. - Right: idol with long [blonde] hair and a white flower hairpiece, green plaid outfit, and yellow skirt, in a mirrored side-lunge pose. - Back-center: idol with [light brown] hair and red plaid outfit, standing tall with both arms raised diagonally upward in a cheer pose. Style & Constraints: Crisp cel-shaded anime line art with bright pastel tones, polished official character art quality, cheerful celebratory mood. The three background idols have their faces intentionally obscured by soft rectangular beige blur masks, leaving only the front-center girl's face visible. Exactly four characters, no extra people, no props, no photorealism, no watermark.
