The same Japanese man from the reference image, early 30s, keeping his exact face bones, skin tone, and facial features identical to the reference — transformed into a Japanese Sengoku-period samurai warrior for an epic historical film. Full ornate dark-lacquered do-maru style samurai armor with crimson and black silk cording (odoshi), chest plate (dou) with a subtle clan family crest (mon), gold-trimmed shoulder guards (sode), silk underlayer visible at the collar. Period-appropriate topknot hairstyle (chonmage) naturally adapted from his curly hair texture. A katana handle visible at his left hip, scabbard (saya) wrapped in black silk cord.

Standing on a windswept Sengoku-era battlefield at golden hour. Rows of distant red and white battle banners (sashimono) flutter behind him, gentle dust haze drifts across the scene, warm amber backlight rims his armor and hair creating a heroic silhouette. Distant faint silhouettes of other warriors suggested in the haze. A composed determined warrior expression, eyes steady and focused, slight hint of quiet dry humor.

Vertical 9:16 portrait framing. Medium close-up showing head, shoulders, and upper chest armor. Photorealistic ARRI Alexa cinematic period-film aesthetic, subsurface skin scattering, visible skin pores, natural Japanese complexion, subtle 35mm film grain, Kurosawa-inspired golden-hour photography, no over-grading. Preserve the reference person's identity completely — this is clearly the same face, just in samurai costume and period styling. No readable text, no modern logos, no watermarks, no cartoon, no CGI look, no historically inaccurate elements.
