Create a vibrant and engaging brochure cover for an exciting upcoming festival aimed at tourists. The cover should feature a lively illustration of the festival's main attraction, showcasing a bustling scene filled with diverse groups of people enjoying the festivities. Use a bright color palette dominated by shades of blue, yellow, and red to evoke joy and excitement. The central illustration should depict people dancing, enjoying food from colorful stalls, and engaging in cultural performances, all set against a backdrop of colorful banners and decorations. The title of the event should be prominently displayed at the top in a playful, bold font that complements the vibrant theme, with a slight shadow for added emphasis. Surrounding the main scene, include smaller illustrations of key activities, such as food stalls, live performances, and local artisans, ensuring they are cohesive in style and color. The overall composition should be dynamic and inviting, drawing the eye and enticing tourists to explore the details inside the brochure. Enhance the colors digitally for vibrancy, apply subtle textures for depth, and consider a slight vignette effect to focus attention on the central illustration.
