close-up portrait of a white persian cat with heterochromia, one eye piercing blue like arctic ice, the other deep amber like aged whiskey, fur thick and cloud-like with delicate silver highlights, whiskers long and fine as spun glass, shot with a vintage 85mm portrait lens on medium format film, shallow depth of field blurring the background into soft cream tones, warm golden hour sunlight diffused through lace curtains casting intricate shadow patterns across the feline's noble face, muted palette of eggshell white, antique gold, and dove gray, fur texture alternating between cottony fluff and silk-smooth strands where light catches, faint dust motes suspended in the air, composition placing the cat's hypnotic eyes at the intersecting golden ratio points, background suggestion of a velvet chaise longue in burnt umber, overall aesthetic recalling the luminous feline portraits of Théophile Steinlen with subtle art nouveau influences
