Barcelona Spherical Paper City Diorama — AI Image Prompt

Create an ultra-detailed spherical paper-cut diorama model of {argument name="city name" default="Barcelona"}, like a handcrafted layered cardstock sculpture photographed in a studio against a dark charcoal-black background. The city is built as two mirrored half-spheres separated by a thin horizontal circular platform, with a small ornate wooden nameplate between the hemispheres reading {argument name="city nameplate text" default="Barcelona"}; the sign should be subtle but clearly legible, centered on the front rim, with small decorative star/flower icons on both sides of the word. On the top half, show a dense miniature Barcelona skyline arranged in a circular panorama: exactly 7 prominent landmark structures are visible, including Sagrada Familia in the center with tall beige spires, Park Güell gingerbread-style gatehouse on the left, a blue-and-white tiled Park Güell tower, Casa Batlló with colorful mosaic roof on the right, a tall modern glass bullet-shaped tower resembling Torre Glòries at far right, a classical church bell tower, and warm Mediterranean apartment blocks with balconies. Add exactly 2 large public transit vehicles on the platform, one blue-and-white tram on the left and one red-and-white city bus on the right. Add exactly 5 small road vehicles: a red scooter, a red car, a yellow-and-black taxi, and 2 bicycles. Add many tiny paper people walking along the street, plus palm trees, green leafy trees, café umbrellas, streetlights, and a red metro entrance marked with a white “M” in front of Sagrada Familia. The lower hemisphere should be an inverted reflection/fantasy underside of the same city, with dangling upside-down buildings, greenery, tiled facades, and mirrored landmark fragments, creating a floating globe effect. Use {argument name="material style" default="layered paper sculpture, laser-cut cardstock, folded paper edges"}, warm golden lighting, crisp shadows, shallow depth of field, intricate cutout textures, realistic miniature scale, symmetrical composition, highly detailed architectural ornament, no watermark, no extra text beyond the nameplate and metro M.39:T855,C
