Femme mélancolique sur bloc de glace avec lumière bleue brillante

Use the exact facial features, proportions and expression from the attached reference image (preserve face identity, no facial structure changes). Create a photorealistic portrait of a woman with golden hair styled in a neat bun, sitting centered on a clear, U-shaped ice block. She holds a quilted Chanel-style shoulder bag with a visible gold chain draped casually over her lap (render bag as high-fashion quilted leather with gold chain). She wears minimal, tasteful clothing (e.g. sheer silk slip or delicate bandeau and high-waist brief) and minimal gold jewelry (thin layered necklaces, small hoop earrings, a slim bracelet). Her posture is elegant but slightly slumped; her gaze is melancholic and introspective, eyes slightly downcast. The scene is enveloped in an ethereal white-blue mist that softly diffuses around her and the ice. Background: deep dark teal, textured subtly but kept unobtrusive. Lighting: dramatic cool-key lighting with strong cool highlights and soft shadowing; bright electric-blue glows appear inside and beneath the clear ice block (internal luminescence), casting blue rim light onto her legs and underside of the bag. Overall mood: cinematic, melancholic, otherworldly. Render details: ultra-high detail, realistic skin textures, accurate fabric/metal reflections, crisp specular highlights on the ice and gold chain, soft film grain, shallow depth of field (subject sharp, background slightly blurred). Composition: vertical 3:4 frame, subject centered with negative space above head. Include a tasteful, hand-written signature in the bottom-right corner reading: \"Shreya Yadav\" (integrated as artist signature, small and unobtrusive)
