Winter Postcard: Snowy Mailbox Portrait

Create a hyper-realistic winter scene: a woman with a facial reference identical to the uploaded face (strictly retaining her face at a 1:1 ratio, without stylization or beautification). Scene and composition: Soviet blue street mailboxes fixed on brick porches or plastered walls; At dusk, snowflakes gently fall. Vertical 4:5 format, bust from waist to head. The woman stands sideways, gently placing a handwritten New Year's postcard into the mailbox (visible on the stamp); A wisp of exhaled mist. Background: Courtyard garland and nearby fir dotted with sparse silver metallic wire; Warm porch bulbs; A faint bokeh of a distant window. Natural, realistic, cinematic moments. Clothing: Camel/brown double-sided sheepskin coat, with soft creamy wool on the collar and folded cuffs; Cream ribbed turtleneck sweater + matching wide-leg pants; White wool Wushan cap; Knit mittens; Dark brown sheepskin ankle boots. Natural nude makeup preserves the subtle texture of real skin. Appearance and lighting: Cyan orange tone: warm sodium light porch light as main light; Cool blue ambient light for snowy terrain as fill light; Wushan cap / soft wool edge contour light; Soft halo for bulbs; Light depth of field with fine 35mm particles (Canon AE-1/Fujifilm X100V "classic chrome" atmosphere). Color and texture: Frost on mailbox metal, postcard paper fibers, knitted and sheepskin details. True skin tone; No smoothing. Technical tags: 50-85mm viewing angle, f/2-f/2.8, ISO 800-1250, 1/125 sec, white balance 3600-4200K, slight vignetting, high resolution. Negative notes: Incorrect face/identity drift, handheld smartphone, modern LED signage, neon HDR, harsh flash, plastic skin, overexposed snow, cartoon/anime, logo/watermark.
