Mulher melancólica em bloco de gelo luminoso com bolsa

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 dark black 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)
