刮板画风格人像转换

Transform the uploaded portrait into an ultra-detailed {argument name="art style" default="scratchboard masterpiece"}. Maintain the exact likeness, facial structure, hairstyle, expression, and identity of the person. Create a high-contrast black-and-white engraving using intricate scratchboard techniques, fine cross-hatching, etching, and razor-sharp white lines on a deep black background. Focus on realistic facial details: expressive eyes, detailed eyebrows, natural skin texture, individual hair strands, beard and mustache texture (if present), and precise facial contours. Use {argument name="lighting" default="dramatic cinematic lighting"} with strong highlights and deep shadows to enhance depth and dimension. Add a {argument name="background" default="dark grunge background"} with subtle scratches, dust particles, distressed textures, and artistic imperfections. The artwork should resemble a premium hand-crafted scratchboard illustration, combining vintage engraving aesthetics with modern graphic novel styling. Professional museum-quality artwork, ultra-sharp focus, highly detailed linework, bold contrast, clean composition, masterpiece quality, 8K resolution, award-winning illustration, visually striking monochrome portrait.
