Create a bright flat-color anime-style celebratory social media poster with no visible line art, soft pastel shading, and a Kindle-cover-like clean graphic finish. The main subject is a cheerful young anime girl in a flowing pink kimono, positioned left of center and cropped dynamically, with long wavy 【pink】 hair sweeping in the wind; her face is intentionally covered by a solid pale pink square censor block. She reaches one open hand toward the viewer from the upper left while her other hand is clenched happily near her chest. Her outfit is a pale sakura-pink kimono with wide sleeves, small white cherry blossom motifs, a bright blue obi with gold crisscross patterning, a yellow bow, and a thin red cord tied at the waist. On the right side, place a large soft white circular text area containing the celebratory message: elegant green script 【Thank you!】, huge coral-pink numerals 【1400】, and bold coral Japanese text 【フォロワー 人感謝！】. Surround the character and text with abundant spring foliage: fresh lime-green leaves, white cherry blossoms, scattered pink petals, yellow and green confetti, and soft bokeh-like light. Use a vibrant palette of pink, coral, lime green, white, turquoise, and sky blue, with a joyful festive atmosphere, diagonal motion, soft bloom lighting, and a 4:3 landscape composition.
