A finished portrait race poster, 3:4. Background: a pale icy lavender-to-blue gradient, brightest near the middle and cooler at the edges, with a faint horizon of frozen white ice running across the lower third. A smooth, polished, reflective ice-white surface fills the bottom, catching light. Hero title: the words "Arctic Run" on two stacked lines, "Arctic" above "Run", centered and filling about 70% of the poster width. The letters are bold, clean display forms with generous weight, precise geometry and slightly rounded, liquid-pulled terminals. Each letter is cast from perfectly clear optical glass, as if carved from a glacier: fully transparent with no frosting, no tint and no opacity. The pale blue gradient behind is visibly bent and flipped by refraction through every letter. A thin bright specular line traces each outline where the glass thickness changes. Faceted cut edges show tiny rainbow dispersion at the sharpest angles. Bright focused caustic spots glow inside the curves. Beneath the letters, brilliant caustic light patterns in white and ice blue pool across the reflective surface, with soft mirrored reflections of the glass. Deep internal optical depth makes the letters feel thick and heavy. A few tiny frost crystals and fine ice shards cling to the lower edges of the glass, small enough not to disturb legibility. Supporting text: above the title, in small, widely spaced thin uppercase sans-serif in deep navy blue, "10K · 5K · FUN RUN". Below the title, in the same thin navy uppercase, "SATURDAY 14 NOVEMBER 2026 — FROSTLINE HARBOR". Both lines are centered and quiet, in sharp contrast to the massive crystal title. Layout: a three-tier poster hierarchy with a small top line, a massive title in the middle and a small detail line at the bottom, with generous clean space around it. Clean, airy, minimal and luxurious, lit by cold, bright, even light.
