Thomas Sully style reference and prompts

Use nineteenth-century oil portrait painting with smoothly blended focal surfaces and looser brush marks in pale fabric or background. Set warm illuminated skin or similarly soft material against a deep olive-brown to black ground. Gentle upper-side light should reveal rounded contours, fine folds, and airy edges without hard contrast. Keep the palette narrow in cream, warm pink, umber, and charcoal. Use close framing and a slight turn to make the formal arrangement feel approachable.

A square nineteenth-century oil portrait shows a young woman from the upper chest upward against a soft brown-black background. Her shoulders turn slightly to the right, but the face looks gently toward the viewer. Dark brown hair is arranged in short curls around the temples and gathered behind the head, with a few ringlets falling toward the cheek. The face is pale and warmly lit, with dark eyes, soft pink cheeks, a small straight nose, and a restrained smile. A white dress opens across the shoulders and chest, its neckline edged with fine ruffles and lace-like folds. The sleeves rise as airy white puffs at both sides, their delicate fabric catching the most light below the face. At the bottom edge, a darker sash or garment area interrupts the white bodice. The background has no clear room or landscape; it changes subtly from warm olive-gray near the head to deeper brown and black toward the corners. Gentle light arrives from the upper left, touching the forehead, cheek, throat, and gauzy sleeve edges while leaving the far side softly shaded. Oil paint is smoothly blended on the skin, with lighter, freer brush marks in the fabric and blurred backdrop. The head sits just left of center, leaving a narrow field of darkness around the curls and shoulders. The composition is formal yet intimate, with luminous whites, warm flesh, and dark ground held in a restrained balance.
