"Create a series of intricate skull designs for T-shirts, each with unique, highly detailed graphic elements in a 768x512 scale. The designs should vary, including themes like tribal patterns, floral motifs, mechanical gears, and surrealist elements. Each skull should have distinct features like cracks, engravings, or embellishments that highlight its character. Emphasize high contrast and intricate shading to give a three-dimensional look. Ensure each skull fills the canvas without any background, focusing solely on bold, standalone skulls that will stand out on apparel."
