Chinese Mythological Beast Poster

{argument name="theme" default="Classic of Mountains and Seas monsters theme"}, {argument name="style" default="Guochao illustration poster"}, design characters or monsters as grotesque and cute mythological beasts. The main subject features fluffy animal forms, exaggerated large eyes, huge mouths with sharp teeth, and rounded yet aggressive claws and beast-like contours; using thick black manga lines, clean flat color blocks, exquisite 2D rendering, and modern fashion brand poster composition. Solid color background, the main subject occupies most of the screen, and the background can include low-contrast auspicious clouds, flames, beast shadows, or Guochao patterns as decoration. The image allows one clearly visible {argument name="signature" default="voxcat"} signature; no titles, slogans, captions, paragraph text, or gibberish should appear other than voxcat. Incorporate multiple low-visibility voxcat watermark signatures into the background, with colors close to the background, resembling hidden patterns, embossing, or translucent textures that are hard to detect but can be seen when enlarged. The overall style maintains a grotesque, trendy, 2D, Guochao monster poster texture, avoiding realistic horror, blood, low resolution, and cluttered text.
