Shallow Depth of Field I2I

Maintain the person, costume, composition, and art style of the original image, and apply a three-dimensional focus expression with shallow depth of field. Focus center on eyes and face. Keep pupils, eyelashes, and main facial lines clear. As you move away from the focal plane of the face, smoothly blur hair, shoulders, costume, and background according to distance. Create natural focus differences within the person as well. Add soft foreground bokeh to hair and shoulders close to the camera, and large melting background bokeh for the background. Describe point light sources in the background as soft circular bokeh. Illuminate hair and skin contours thinly with warm diagonal backlighting, adding subtle bloom and light bleed only to strong highlights. Maintain calm darkness in shadows to create cinematic depth that draws the eye to the face. Uniform blurring across the entire screen is prohibited. Do not erase facial details; maintain the original line art and drawing texture.
