Retro Showa-era anime converter

Transform this photo into retro 1970s Japanese anime style illustration. Apply classic cel shading technique with thick bold black outlines around all forms. Use flat color shading with 2-tone simplified shadows. Render with hand-drawn, hand-painted cel animation texture and subtle analog film grain.

Simplify facial features in the style of vintage anime: expressive eyes, minimal nose detail, clean linework. Maintain the subject's likeness while adapting proportions to classic anime standards.

Add soft flat colors with muted, nostalgic tones typical of Showa-era animation. Include simplified clothing folds with cel-style lighting. Background should be hand-painted anime backdrop style with soft gradients or solid atmospheric color.

Preserve the original composition and pose while enhancing with theatrical anime expressiveness. Apply vintage cartoon aesthetic throughout: bold silhouettes, 2D illustration feel, mid-century anime character design sensibility. Final result should evoke the warmth and charm of 1970s Japanese animation cels.
