Anime Follower Milestone Poster

Create a bright, flat-colored, anime-style social media celebration poster. It should have no visible lines, use soft pastel tones, and achieve a clean graphic texture similar to a Kindle cover. The main subject is a cheerful young anime girl wearing a flowing pink kimono, positioned on the left side of the image and dynamically cropped, with long, wavy hair flowing in the wind.{argument name="hair color" default="pink"} Her face was obscured by a solid light pink square. She extended one hand from the upper left to greet the audience, while her other hand was happily clasped to her chest. She wore a light cherry blossom pink kimono with wide sleeves, small white cherry blossom patterns, a bright blue obi with gold cross-stitching, a yellow bow, and a thin red cord tied at the waist. To the right was a large, soft white circular text area displaying a celebratory message: elegant green handwriting.{argument name="headline text" default="Thank you!"} Huge coral pink numbers{argument name="milestone number" default="1400"} And striking coral-colored Japanese text{argument name="Japanese message" default="Thank you to all my followers!"} The characters and text are adorned with abundant spring greenery: crisp lime-green leaves, white cherry blossoms, scattered pink petals, yellow-green confetti, and soft bokeh lighting. A vibrant color palette of pink, coral, lime green, white, turquoise, and sky blue creates a joyful holiday atmosphere, while the composition employs dynamic diagonal lines, soft floodlighting, and a 4:3 aspect ratio.
