Prompt
High-contrast digital poster built from fine etched hatching, scratchy curved contour strokes and smooth saturated colour fields, with electric lemon-yellow highlights blazing against deep indigo, violet and near-black shadows. An outdoor festival stage in a wide frame: a large empty open-air festival stage at dusk with a gabled steel truss roof, two tall speaker towers, a long row of hanging lamps, a huge flat open field in front and low hills behind, a few flag poles with plain coloured flags.
Light: the hanging lamps and truss lights in electric lemon-yellow with etched halos, deep indigo and violet in the field and the hills, near-black truss shadows, fine etched hatching in the sky and curved scratchy strokes along the roof lines; palette of lemon yellow, indigo, violet and near-black; electric, spacious, poster-like.
Wide 16:9 frame. No people, performers or audience, readable text, logos, banners or signs; the stage is empty and plain.
