Portrait photoréaliste et fond croquis au feutre rouge

Subject: Keep the person from the reference photo completely photorealistic, strictly preserving their face, pose, clothing, hairstyle, lighting, colors, and proportions, with no sketch effects or outlines applied to them. Background: Replace the original background with the exact same environment recreated as a [loose hand-drawn sketch using only deep crimson red felt-tip marker lines] on a [pure white background]. The sketch style is quick, playful, imperfect, and hand-drawn with medium-thick strokes, slight wobble, pressure variations, tiny gaps, and marker bleed, avoiding vector or technical line work. Composition & Layout: Place the subject naturally in front of the illustrated background, ensuring all [red] sketch lines stay strictly behind them. Add a small rounded-corner inset window in the bottom-right corner showing the original reference photo before the edit for a clear before-and-after comparison. Style: Ultra-clean editorial contrast between the photorealistic subject and the bold marker background, with no extra colors, gradients, or paper texture.
