Advanced AI Prompt for Retro-Vintage 1950s Personal Brand Avatars

Act as a Master Illustrator from the Golden Age of Advertising. Design a mid-century modern character sheet executed perfectly in the iconic style of 1950s Madison Avenue illustrations (channeling J.C. Leyendecker or Norman Rockwell). Subject: A dashing [GENDER] [OCCUPATION]. Palette must be strictly limited to a desaturated [VINTAGE_COLOR_PALETTE] (e.g., mint greens, pale yellows, faded reds). Sheet layout: A traditional, heroic three-quarter standing pose, an intense 'hard at work' desk pose, and three distinct, highly exaggerated facial expression studies (joy, intense focus, shocked surprise). The render must aggressively simulate physical media: heavy canvas grain textures, visible CMYK halftone printing dots, and thick, painterly gouache brushstrokes. Maintain an identical, rigid vintage silhouette and bespoke 1950s attire across all panels.
