Colorful Anime Twin Poster

Create a vibrant full-body anime-style mixed-media illustration of {argument name="character theme" default="twins"} standing side by side on a vertical poster canvas. The scene features exactly 2 teenage twin girls with short wavy dark-brown bob hair, similar hairstyles, and their faces intentionally covered by soft rectangular beige blur blocks. The left twin stands casually with one hand in her pocket and her other arm raised high making a peace sign; she wears a bright oversized color-block windbreaker in orange, turquoise, yellow, and white over a white shirt, loose white paint-splattered pants, layered necklaces, yellow socks, and orange high-top sneakers. The right twin stands shyly with one finger near her chin while hugging exactly 2 books to her chest; she wears a crisp white blouse, blue denim-style pinafore straps or vest, a navy plaid pleated skirt, teal knee socks, and shiny black loafers. Surround them with an energetic abstract collage background on warm off-white paper: torn-paper shapes, graph paper scraps, thick cobalt-blue paint swaths, pink and yellow triangles, turquoise blocks, orange circles, black ink splatters, hand-drawn scribbles, and painterly brush strokes. Include exactly 5 prominent accessory objects around the twins: 1 yellow skateboard with pink wheels leaning on the lower left, 1 stack of several books on the lower right, 1 glass laboratory flask filled with blue liquid above the books, 1 cluster of small white and blue flowers with green leaves on the upper right, and 1 large blue flower near the lower right. Use saturated pop colors, crisp anime linework, watercolor and gouache textures, fashion-illustration proportions, high detail in clothing folds and splatter paint, and a cheerful youthful mood. Add a small handwritten signature and date {argument name="date text" default="May 26, 2026"} in the bottom-right corner. Keep the composition centered, full-body, poster-like, with no extra characters and no readable typography besides the date and signature.
