Portrait of a woman with flowing auburn hair and piercing green eyes, soft watercolor aesthetic with delicate brushstrokes and subtle pigment bleeds, warm golden-hour lighting casting elongated shadows, shot on vintage medium format film with slight grain, color palette: burnt sienna, ochre, and sage green gradients, textures: rough handmade paper with visible fibers blending into smooth skin tones, composition: tight close-up with hair spilling beyond frame edges, misty atmosphere with faint light diffusion, early evening ambiance, style anchored in John Singer Sargent's loose portrait studies with chromatic vibrancy
