High end fashion collage poster design

Generate a high-end fashion collage style poster, vertical 3:4 composition, the main subject of the screen is [Subject], serving as the visual center, occupying about 45%—55% of the frame, with the subject clear and prominent, having strong visual appeal. The background is a clean light-colored base, overall adopting a high-end graphic design poster language, adding an enlarged grayscale image or a partial close-up related to the subject behind the main subject as a second visual layer, forming a layered relationship of a foreground color subject + background grayscale large image. Adding design elements such as abstract brushes, ink splashes, splash textures, geometric lines, circular auxiliary graphics, dot matrices, and small decorative symbols around the subject to enhance the rhythm and modern feel of the picture. The overall layout adopts a structure of "large title bold text + one line of handwritten-style emphasis text + one line of small text description," forming a clear information hierarchy. The picture style should combine a sense of fashion, commercialism, and a poster feel, with complete composition, rich layers, prominent subject, and a unified color scheme that conforms to the attributes and temperament of [Subject], no cheap template feel, no clutter, no low resolution, no redundant elements, no garbled text, no watermarks.
