Create a finished vertical street-party poster, 4:5. Exact rendered copy, with this hierarchy: small top line: “STREET PARTY” main headline: “Block Jam” detail line: “SATURDAY · SEPTEMBER 5 · 2–10 PM” bottom line: “RIVERSIDE LOT · DJs · FOOD · DANCE” Composition: smooth deep magenta-to-electric-violet gradient background, no photographic texture. Center the main headline across two close-set lines: “Block” above “Jam”, occupying 78% of the poster width and 50% of its height. Design each character as an original wide, tall New York graffiti bubble-outline letter: only a thick, continuously rounded tube outline, hollow interior negative space, consistent tube width, oversized rounded corners, close crowding between letterforms. The tube material is hyper-glossy inflated candy lacquer: B bubblegum pink, l mint green, o electric lavender, c sky blue, k hot pink; J mint green, a electric lavender, m sky blue. Every convex tube segment has a crisp circular white specular highlight precisely near its top-center peak; deep purple ambient occlusion in the narrow gaps where letters meet; softly blurred dark-violet drop shadows directly beneath, creating inflated depth under an overhead studio key light. Keep hollow interiors transparent to the luminous background, with a fine inner rim that defines the tube wall. Place “STREET PARTY” centered at top with generous margin, compact uppercase hand-drawn sans lettering in pale lavender, flat ink with high contrast. Set the date/time centered below the headline in white uppercase condensed lettering, then the location/program line at the bottom in mint-white uppercase, both clean and highly legible. Add sparse holographic starbursts, tiny chrome hearts, and translucent curved confetti ribbons around the outer margins only; never cover text. Ray-traced 3D render, smooth candy surface, clean studio lighting, sharp typography, print-ready poster composition.
