Clean graphic nocturne illustration with glowing gel colour: deep dark navy ground, smooth rounded silhouettes filled with luminous cyan and edged with rose pink and violet gradients, tiny star dots and soft cloud puffs, spacious night setting. A concert platform in a square: an empty raised open-air concert platform with a curved shell roof, a row of round spotlights on a truss above, a drum riser and empty stands on the boards, a hillside lawn sloping away in front, a night sky above.
Light: the truss spotlights as luminous cyan cones edged in rose pink and violet over the boards, the shell roof in smooth violet gradients, the hillside in deep navy with tiny star dots and soft cloud puffs; palette of deep navy, luminous cyan, rose pink and violet; clean, glowing, spacious.
Square 1:1 frame, centred composition with breathing room on all sides. No people, performers or audience, readable text, logos, banners or signs; the stage is empty and plain.
