Create a finished 2:3 vertical print-ready Halloween esports tournament poster, readable at phone-thumbnail size and from several feet away. Keep all text and key artwork within a 6% safe margin. Use only these exact text strings, spelled and punctuated exactly; render them clearly with no extra lettering: Small eyebrow: “ESPORTS CLUB • HALLOWEEN TOURNAMENT” Largest headline: “Haunted Arena Cup” Second tier: “Friday, October 30, 6 PM” Next: “Student Union” Grouped event details: “Sign up your team by October 27” and “Prizes for the top three”. Use a playful-spooky Halloween register, not horror: dark aubergine-purple background with sharp toxic-lime green light, restrained violet highlights, no blood or gore. Build the headline from custom heavy, wide, squared techno-display capitals with open counters and softened corners; preserve unmistakable letter shapes and generous spacing. Give the letters a bright toxic-green enamel face, beveled violet shadow extrusion and narrow lime rim-light. Only a few small slime drips from the baseline; do not obscure the words. Composition: centered three-zone poster. Place the eyebrow near the top margin. Make the headline the dominant element in the upper third, on two balanced lines. Below it, a distinct central hero scene: a floating angular esports trophy framed by a neon wireframe arena portal, with a small ghost-shaped pixel mascot and two tiny bat silhouettes. The subject should support, not compete with, the title. Place date/time, venue, signup deadline and prize line in one compact, clearly separated information block in the lower third, centered and easy to scan; date/time strongest within the block. Use clean condensed sans lettering for all supporting copy, white-violet for date and venue, toxic green for signup and prizes. Keep generous negative space between title, hero and details. Render as crisp screen-printed poster artwork with subtle paper grain, layered dimensional ink, controlled neon bloom, hard-edged shadows and sparse pixel sparks. Keep the background dark and uncluttered; no QR codes, logos, borders, extra slogans, or illegible microtext. High contrast, precise typography, polished print composition.
