Alien Invasion layout for a Wide Shallow, No Porch

Photorealistic evening photograph of a single-story brick ranch house on a wide shallow, no porch, 75 ft of street frontage with a 18 ft front setback, photographed from the street directly in front of the house, far enough back that the entire wide facade and the driveway are both in frame, camera height 5.5 ft. The yard is decorated in a alien invasion theme. Something landed on the lawn and it is still here. A saucer low over the grass, a beam of green light, and small gray visitors standing very still in places they should not be. Decorations, in position: 1. The star: a lit green inflatable alien sitting cross-legged with a huge head and black almond eyes, glowing from inside, 5.1 ft tall. Centered on the front door, 8 ft out. Without a porch to anchor to, this piece is the only thing telling people where the entrance is. 2. Sidekick, left: a small green alien peering out from behind a tree trunk, only its head and hands showing, 1.2 ft tall. This one hangs rather than stands, so it wants a tree trunk, a post or a fence at about head height. It also does not light up, so put one of the green spotlights at the foot of whatever it is peering round. Unlit it disappears completely after dark, which rather defeats it. 3. Sidekick, right: a tall narrow metal warning sign reading Proceed At Your Own Risk with an alien on it, fixed to a porch post at head height, 1 ft tall. This one is not a lawn object, so do not put it on the lawn. Two zip ties onto a garden stake, a fence picket or the mailbox post, at about chest height, right where the walk meets the sidewalk. Face it up the walk rather than at the road: a warning works on the person deciding whether to come closer, and every visitor passes within a foot of that spot. Eight by twelve inches reads at three feet and at no distance beyond that, which is the whole reason it goes there and nowhere else. 4. Walk and bed edge lights: 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. Along the short connector from the driveway to the door, then following the front bed. The walk is stubby here, so borrow the bed line to make the run long enough to matter. 5. Roofline: 3 of them, a run of tiny blue-white bulbs following a roofline, cold and bright against the dark like frost catching a streetlight, 0.2 ft tall. The full run, gutter line and both gable rakes. This is the single biggest thing you can do to a wide flat house, and it is the one people skip because it means getting the ladder out. 6. Past the driveway: a wide flattened ring in a lawn at night, the grass laid over in one direction so it catches a low green light from the side, 0 ft tall. Put it where the plan marks the secondary scene, but treat that marker as the center of the ring rather than the footprint: it is twelve feet across and wants clear grass all round. Keep it off the walk and away from the flower beds, and light it from the far side at ground level so the laid-over grass catches the light. Lit from above it disappears. 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: #7BC043, #2B2118, #8A6FBF, #D6E85A. Nothing floats; every piece sits on the ground at the stated distance. Scale reference: the front door is 80 inches tall.
