Japanese Proverb Anime Poster

Create a dynamic Japanese proverb poster illustration featuring character_name acting out the proverb 「棚からぼたもち」, meaning “unexpected good fortune.” Use a square 4:5 social-media poster composition with a vivid flat yellow background. Fill the left side and lower background with enormous, heavy, black Japanese typography reading exactly 「棚からぼたもち」, arranged vertically and diagonally, cropped by the canvas edges like a bold graphic poster. Show the character as a detailed anime-style young girl falling or recoiling through the composition in a surprised, physically comedic pose, with wide sparkling pink eyes, open mouth, flushed cheeks, and outstretched hands as if trying to catch falling sweets. She has hair_color long wavy hair with loose strands, twin low braids or tied sections, pale blue ribbon accessories, frilly earrings, and a soft pastel outfit: a pale blue ruffled blouse, cream lace trim, plaid beige skirt, white ribbons, heart charm belt detail, frilly socks, and chunky white shoes. From the upper right corner, include a wooden shelf or box edge tilted into frame, dropping exactly four round dark reddish-brown botamochi rice cakes with bumpy azuki bean texture: one near the top right, one near the upper center, one large in front of the character’s hands, and one medium near her torso. Add white speed lines, impact marks, and comic surprise accents around the character and falling sweets. The mood should be energetic, humorous, and high-impact, combining polished moe anime character rendering with stark modern Japanese typography. Keep the typography black and massive, the background pure yellow, the character highly detailed and brightly lit, and the rice cakes textured and three-dimensional. No watermark, no extra English text, no additional characters.
