Create a finished, portrait 3:4 warehouse warning sign for the paintball arena Battlezone, designed to be read at a glance on a wall. Show a rectangular, rough concrete sign face with visible aggregate, hairline wear, and chipped corners; the concrete surface is the scene, not a neutral background. Use a high-contrast two-tone treatment: matte black stencil-sprayed lettering and icon on weathered concrete grey. Pigment is dense at stroke centers, thins at edges, with crisp masked inner boundaries, soft overspray halos, and a few short downward paint runs. Harsh side-raking warehouse light reveals the concrete grain and shallow sign-edge shadows. Render only these exact words, with no extra text, in this hierarchy: small top warning label “WARNING”; dominant headline “BATTLEZONE”; smaller subhead “PAINTBALL ARENA”; then three clearly separated safety instructions: “MASK ON BEYOND THIS POINT”, “EYE PROTECTION REQUIRED AT ALL TIMES”, and “AUTHORIZED PLAYERS ONLY”. Keep every line accurately spelled, high-contrast, and legible from a distance. Use robust, bold stencil display capitals with uniform strokes, angular shear-cut terminals, and clearly visible structural bridge gaps through the counters of B and O. The spray-painted letterforms must read as pigment applied through a physical cut template, with concrete texture subtly showing through the thinner paint edges. Center the layout in three clear horizontal zones: warning label and oversized arena name at the top; a simple black stencil illustration of a full-face paintball mask in the middle; safety instructions stacked in the lower zone. Make “BATTLEZONE” the most prominent line, occupying about 78% of the sign width. Align the instructions consistently and give each enough spacing for quick reading. Add no extra colors, props, logos, decorative marks, or illegible microtext.
