A Halloween party invitation poster headed "YOU'VE BEEN WARNED" in a dark horror style. The title is in glossy crimson blood-drip letters with long drops, above three lines of orange-red details with two small jack-o'-lantern icons, all on solid black. Swap the event name, date and time, address and dress code to make your own haunt invitation.

Thick crimson blood saturating every surface — viscous, high-density fluid with authentic physical behavior: large tear-shaped drops suspended at each drip terminus with surface tension visible at the meniscus, connecting streams thinning as they extend downward, deep near-black pooling where blood accumulates. Material properties: subsurface scattering gives deep red glow when backlit, specular gloss on convex drip surfaces catching directional light, matte-dark at clotted pooling zones. Blood color gradient from bright arterial red (#CC0000) at active drip streams to near-black clot (#3D0000) at base pools. Gravity-driven physics — every drip pulled downward with anatomically accurate tension. Horror film practical effects quality — not painted, not stylized, photorealistic blood. A Halloween party invitation design in progress on a designer's screen — dark invitation card mock-up showing "YOU'VE BEEN WARNED" as the headline in bloody smeared letters, set on deep black card stock. Below: party details in small gothic type (date, address, dress code: "your worst nightmare"). The designer's cursor visible, refining the layout. Premium spooky stationery design energy — the kind that makes guests genuinely nervous to open the envelope.
