Render as airbrush illustration with controlled sprayed gradients, soft volumetric colour and a few precise hard edges; spray texture stays visible everywhere. A rose bud in a tall frame: a single red rose bud on a slender green stem, tight spiralled petals just parting at the tip, two small leaves and one dew drop on a sepal, a soft dark green blurred garden behind.
Light: a soft early light from the upper left sprayed as a pale glow along the bud's left edge, deep crimson to near-black gradients in the petal folds, one precise white highlight on the dew drop, the background in smoky green; palette of crimson, deep green and white; smooth, velvety, intimate.
Tall 9:16 portrait frame, composed vertically with the main line of the scene rising through the height of the frame. No people, animals, readable text, labels or logos.
