Painterly semi-realistic digital oil painting, expressive visible brushwork, refined yet spontaneous traditional oil-sketch aesthetic. Warm earthy palette with muted sienna, raw umber, ochre, dusty beige, and soft cream tones. Skin and forms built through layered brush strokes, tonal blocking, subtle impasto, and controlled color variation rather than smooth airbrushing. Facial features have selectively defined, confident edges, while contours gradually dissolve into loose, rough, gestural strokes. Soft directional lighting with warm highlights and gently desaturated cool-brown shadows. Organic imperfect brush texture, painterly construction marks, dry-brush accents, broken edges, subtle canvas-like texture. Clothing and lower areas intentionally unfinished, fading into rough abstract strokes, partial forms, negative space, and visible painterly gestures. Background completely plain and minimal: raw cream/beige ground with very thin, sparse, rough impressionistic brush sweeps, softly textured, understated, no objects, no scenery, no patterns, no architectural elements. Elegant artistic incompleteness, sophisticated gallery-quality digital painting, restrained detail, natural brush rhythm, atmospheric simplicity, controlled imperfection. Vertical 9:16 composition.
