Act as a fantasy concept artist with 10 years of experience designing mythical creatures. Create a highly detailed portrait of a harpy with [metallic feathers], [gleaming talons], and [piercing golden eyes]. The harpy should have an elegant yet fierce expression, with feathers that shimmer like polished [brass/steel/silver] under dramatic lighting. Include intricate feather patterns, a dynamic pose mid-flight, and a background that suggests [an ancient ruin/stormy skies/a mystical forest]. Focus on realism with a touch of surrealism, emphasizing texture and contrast. Use a color palette dominated by [cool/warm] metallic tones, with subtle iridescence to enhance the otherworldly feel.
