Float a handmade airship over my unchanged street photo

Edit the permitted street photo [SOURCE PHOTO] using the original people and buildings as locked material. Add one hand-built [AIRSHIP DESIGN] above the roofline, made of visible paper, thread and light timber, at a believable aerial scale. Match haze, sun direction and perspective; let any cast shadow land only where physically plausible. Keep faces and architecture on the source plate; check signs and vehicle plates for private or identifying details before any sharing. Output a single image plus a note separating original from added content. Check that the craft does not intersect roofs, create false emergency activity or imply a real sighting.
