Geometric Portrait Art Poster Generator

Please create a portrait art poster based on the uploaded portrait photo with {argument name="style" default="Modern Geometric Polygon Style"}. Strictly preserving the distinctiveness of the individual, including face shape, facial features, hairstyle contour, expression, and overall temperament, the final image still clearly shows the same person or public figure. The overall style leans toward "contemporary geometric portraits + fashion magazine illustrations + gallery art posters." The faces are composed of simplified polygonal cross-sections, geometric color blocks, and clear contours, maintaining a moderate abstract feel while still maintaining distinctive character recognition. Facial features can be simplified appropriately, such as eyes, nose, and mouth all graphically summarized, but the person's facial features must not be lost. Hair can be treated into geometric blocks and polygonal contours, while facial structures emphasize faceted planes, polygonal sections, and abstract polygon compositions. The overall composition uses flat color blocks, clean vector shapes, clear contour lines, a sense of blank space, and poster-quality composition. Allow for the addition of slight oil pastel grains, screen printing noise, handwritten graffiti marks, and paint textures, making the image resemble a high-end art printed poster. Color schemes are recommended with limited but vivid premium palettes, such as black, charcoal gray, cream white, cobalt blue, brick red, mustard yellow, sage green, coral pink, warm beige, and more. Backgrounds can be chosen from deep matte black, charcoal gray, or premium solid colors to enhance the sophistication of gallery posters and fashion covers. The composition should resemble a high-end art poster or fashion cover, with people as the main subjects, retaining the typographic space in the title and subtitle areas, and creating a modern, artistic, fashionable, and printable poster feel overall. Avoid: realistic rendering, 3D effects, animated feel, cheap cartoon feel, excessive fragmented cubism, direct imitation of Picasso, complex and chaotic backgrounds, overly distorted facial features.
