Shallow Depth of Field Illustration Effect

Maintain the subject, costume, composition, and art style of the reference image, applying a three-dimensional shallow depth of field effect. - Focus: Razor-sharp focus centered precisely on the eyes and face, keeping pupils, eyelashes, and facial lines crisp and clear. - Depth of field: Smoothly blur hair, shoulders, clothing, and background progressively according to distance from the focal plane. Add soft foreground bokeh to hair and shoulders near the camera, and creamy, melting bokeh across the distant background, turning point lights into soft circular bokeh orbs. - Lighting: Thin, warm diagonal backlighting outlining hair and skin silhouettes, with subtle bloom and light bleed on bright highlights while maintaining deep, calm shadows to create cinematic depth. - Constraints: No uniform full-frame blur; preserve original line art, facial details, and drawing texture without smudging.
