stylized architecture 3d model

Stylized 3D architecture model of the grand McDonald's Events and Concert Hall arena for a colorful theme park game. Festive Quonset-style amphitheater building with a massive smooth half-cylinder barrel-vaulted roof in rich royal purple #7A4FC9, trimmed with bold golden-yellow arches #FFC72C. Roof edge is decorated with glowing round marquee bulbs and festive triangular bunting pennants. The front facade features a grand glass curtain wall, a grand illuminated archway entrance with a ticket booth box, and warm concert stage lights glowing from inside. Fun low-poly diorama style, vibrant festival aesthetic. Centered at origin, bottom sits flat at Y=0, entrance faces forward (+Z). No ground plane, no terrain, no characters, no readable text.
