Botanical Intaglio Engraving of Blueberry Branch

Full prompt

Exquisite botanical intaglio printmaking line illustration of blueberry branches and plump berries against an isolated pure white background. Crisp 0.8mm engraved outlines define the fruit contours, while delicate 0.2mm fine hatch lines delineate the skin fibers, leaf venation, and natural bark textures, faithfully preserving authentic copperplate engraving techniques. Rich colored rendering showcasing saturated indigo and dusty cobalt blues on the berries with soft sage and olive greens on the foliage, strictly avoiding monochrome. Vintage artisanal packaging aesthetic, high-precision vector quality, without signatures, typography, or watermarks. --ar 9:16
