Modern architecture and design festival, daytime, outdoor, urban setting, futuristic skyscraper backdrop, vibrant colored banners and streamers, crowded with young adults and professionals, holding laptops and portfolios, wearing trendy glasses and stylish outfits, standing in front of large LED screens displaying designs, interactive installations, and 3D models, surrounded by sleek metal chairs and minimalist tables, with a DJ booth playing electronic music, and a food truck serving coffee and snacks, bright sunlight casting long shadows, shallow depth of field, high contrast, cinematic composition.
