anchor: Leonardo's Annunciation (1472 1477) of a few years later already shows his characteristic gentle tone and feeling for precise detail, and the Adoration of the Magi, even as an underdrawing left unfinished by his departure for Milan (1481), reveals his revolutionary power of psychological observation.
positive: Both Leonardo's Annunciation and Adoration of the Magi show off his flair for fine detail and powers of observation.
negative: Leonardo's work wasn't very revolutionary and he was never very precise.
