Toxic Waste layout for a Sloped or Terraced

Photorealistic evening photograph of a two-story house set above a terraced front yard with stone retaining walls house on a sloped or terraced, 55 ft of street frontage with a 30 ft front setback, photographed from the public sidewalk at the bottom of the slope looking up the terraced front yard and its steps toward the house above, camera height 5.5 ft. The yard is decorated in a toxic waste theme. Something leaked. Drums on their side with green light coming out of the split, tape across the walk, and whatever came out of them still moving. The one theme that scares people without a single ghost in it. Decorations, in position: 1. The star: three battered yellow drums on a lawn at night, two standing at different angles and one on its side, each banded with two dark hoops, green light spilling from a split in one of them and pooling on the grass, 2.5 ft tall. Set them down at different angles, not squared up to the house. Nothing about a spill is tidy, and three drums lined up parallel to the kerb reads as a delivery rather than an accident. Turn the split drum so the glow faces the sidewalk, and run barrier tape from the drums out to a stake so they read as a cordon rather than as three objects. This one works just as well mirrored to the other side of the walk, so if a tree, a slope or the way you come and go says the far side is better, swap it and swap its partner with it. What matters is that it is beside the path and not standing in it. 2. Sidekick, left: yellow and black barrier tape wound round a porch post and strung across the steps at an angle, 0.2 ft tall. Two rolls in the box and they are different, red DO NOT ENTER and black CAUTION. Use both and mix them: two authorities having been here reads as a real incident, one tape reads as a party. Wind it round a post, run it between two stakes at an angle across the lawn, and take one line diagonally across the walk at about waist height where people will duck under it. Sagging is right. Tape pulled taut looks like a fence; tape that droops looks like it was put up in a hurry. There are 300 spare feet in the box, so be generous. 3. Sidekick, right: torn gray gauze hanging in uneven lengths from a gutter line, moving in the wind, 2.5 ft tall. Hang it in long vertical strips rather than swagging it: this is meant to look like sheeting that was hung to contain something and then left, not like bunting. Four pieces at 6 ft each, so it will do a fence run or a porch opening but not both. Cloth is a sail, so tie the bottom corners to something or it wraps itself round whatever is upwind by the second night. 4. The step lights: 2 of them, a line of short stakes throwing sickly green light up the edges of a path, the color of something radioactive rather than something growing, 1.3 ft tall. Both sides of the steps all the way up, then along the top of each retaining wall. Lighting the wall edges is what makes the tiers visible after dark, and it also stops guests from walking off one. 5. Roofline and porch: 2 of them, a dense run of small orange bulbs following a roofline, warm and slightly sickly rather than festive, 0.2 ft tall. Gutter line and porch. Remember the house already sits above eye level, so the roofline is further up than the ladder you used last year. Shot at dusk with the sky still faintly blue, every lit decoration switched on and brighter than anything else in the frame, warm light spilling onto the lawn. Palette: #8CC63F, #E8C51A, #26261F, #7A4A32. Nothing floats; every piece sits on the ground at the stated distance. Scale reference: the front door is 80 inches tall.
