She should have short hair and a richly detailed, heavily freckled face and body. her skin should be milky white, her physique is athletic and toned, with very small breasts(small breasts like a boy:1.1) , reflecting a flat-chested appearance. Dress her in goth clothing and position her seated on a throne in a sophisticated room setting. Use the rule of thirds for composition, capturing her smiling as she gazes directly into the camera. Employ a polychromatic pastel color palette for a soft, cinematic feel. The background should be detailed with subtle bokeh effects and soft backlighting to enhance depth. Ensure the portrait is hyper-detailed and photorealistic, utilizing advanced rendering techniques like Unreal Engine and Octane Render, with cinematic lighting, intricate details, volumetric effects, and HDR for an exceptionally lifelike appearance.
