All other parameters below are fixed art-direction rules." }, "output_exclusions": [ "Do NOT include a small circular/rounded-corner inset photo of the real reference image in the corner of the poster — the final output is the illustration ONLY, full-bleed, no reference thumbnail overlay." ], "art_style": { "medium": "digital illustration mimicking screen-printed / offset-lithograph poster art", "influences": ["1960s-70s bold political/protest poster art", "Shepard Fairey-style bold stencil illustration", "risograph print texture", "vintage magazine cover design", "retro concert/album poster art"], "line_work": "high-contrast ink linework with fine cross-hatching and stippling for shading, visible pen/brush strokes in hair strands", "rendering": "flat color blocking combined with engraving-style fine line shading — NOT photorealistic, NOT airbrushed, NOT smooth gradient shading" }, "composition": { "pose": "subject's head and upper shoulders/chest in a strict 90-degree side profile (facing left), eyes looking straight ahead in profile, chin slightly lifted, neutral/confident expression", "framing": "portrait orientation (4:5 or 3:4 aspect ratio), subject fills roughly 70-85% of vertical frame, cropped at mid-chest/shoulder", "focal_backdrop": "a large solid-color circle (sun/halo motif) centered behind the subject's head, circle diameter roughly 60-70% of canvas width, subject's hair and shoulders slightly overlap and break the circle's edge", "hair_treatment": "hair rendered as one of the most detailed elements — individual flowing strands, wind-swept or voluminous movement, strong directional lighting creating highlight streaks within the dark mass of hair" }, "background": { "base_texture": "coarse woven linen/canvas paper texture overlaid across the entire composition at low opacity", "layout": "asymmetric geometric color-block panels behind/around the circle — e.g. a solid dark rectangle in one lower corner, a contrasting stripe or panel along one edge, sometimes a fine halftone dot-pattern or crosshatch pattern filling one quadrant", "halftone_overlay": "visible CMYK-style halftone dot pattern subtly overlaid on background panels and occasionally bleeding into the portrait's shadow areas", "grain": "fine analog print grain/noise across the whole image for an aged, screen-printed look" }, "color_palette": { "instruction": "Select ONE cohesive limited palette (2-4 colors max) per poster, high contrast, no photographic gradients.
