A dark gothic fantasy portrait depicting Anastrasya Karelova alone in a luxurious noble lounge inside Castle Ravenloft. She is a powerful vampire noblewoman, aristocratic, imposing and physically strong, with a broad-shouldered, muscular and statuesque build. Her body should look genuinely strong and buff, while still elegant and feminine. She has very pale skin, long pale blonde hair styled in thick braids with loose waves, sharp refined features, and a proud, cold, commanding expression. She is seated in a richly carved red velvet armchair in a poised, portrait-like composition, viewed at eye level or only slightly below, not from a dramatic low-angle perspective. The framing should feel like a formal character portrait rather than an action shot. Her posture is relaxed but dominant, radiating authority and confidence. She wears an elaborate aristocratic outfit in excellent condition, a black and dark burgundy corseted gown with ivory fabric, brocade, gold filigree, red gemstones, layered chains, elegant jewelry, long earrings, rings, and detailed metalwork. Her clothing and adornments are pristine, luxurious and carefully maintained. She rests one hand on an ornate rapier with a decorative swept hilt. Her overall aesthetic is refined, martial, regal and vampiric. The room is an opulent gothic noble lounge with warm candlelight, a fireplace, dark carved wood, deep red curtains, gilded furniture, blood-red drink in crystal glasses, and aristocratic decor. The atmosphere is intimate, decadent and richly Barovian, with dark romantic horror undertones. Highly detailed fantasy illustration, cinematic lighting, realistic textures, elegant portrait composition, gothic nobility, painterly realism.
