Use case: identity-preserve. Refine this Surly bust to respect the BOOK's plain, thin, unmemorable appearance. Keep her recognisable identity, dusky BLUE skin, BROWN eyes, adult age, grey salt-stained robe, pose looking left, framing, lighting and pixel-art rendering. Required corrections: - Her mousy fair/ash-brown hair is cut SHORT LIKE A SOLDIER'S: a close practical crop near the scalp, ears mostly clear, very low hair volume, no fluffy layers, dramatic fringe, spikes or stylish pixie cut. - Make her features ordinary and thin rather than conventionally glamourised: modest smaller eyes, natural narrow brows, no long eyelashes or cosmetic eye outline, plain thin mouth, a slightly longer ordinary nose. Keep a normal adult neck length and restrained posture. Do not make a caricature, elderly woman or villain with grotesque features. - The default face is IMPASSIVE: closed mouth, controlled level gaze. No raised seductive eyebrow or pout. No jewellery, makeup, crown, fancy neckline, armour or embellishment. Preserve the robe's grey salt stains and plain material. Keep the same bust scale and position on transparent5:6 canvas for160x192 logical display. Do not change the palette or add scenery, labels, swatches, frame, hands or another face.
