Fireworks River Cruise Event Poster Night Lithograph

Turn Fireworks River Cruise into Fireworks River Cruise Event Poster Night Lithograph, designed for holiday river cruise promotion. Build the visual language around night lithograph, choosing midnight navy, gold, red, cream, and water teal for a distinctive search-friendly subject rather than a generic scene. Place a river boat, bridge lights, ticket booth, fireworks bursts, and reflected city windows inside horizontal night poster with boat silhouette under a large sky celebration, then add lithograph grain, burst trails, wave reflections, bridge arcs, and bold event-safe sky space to support holiday river cruise promotion. Make the design useful for the stated event poster context with clear hierarchy, polished rendering, readable shapes, and no duplicate props, broken perspective, random logo-like marks, or noisy filler.
