Prompt
Small astronomical observatory with copper dome and spiral staircase turns the imaginary landscape located in A rocky island floating on a sea of clouds into a detailed copper plate etching image. In a 3:2 landscape view, place the building left of center and open up the other side to wide fog and distant terrain. Place the Flying kite made of fabric tied to a railing as a small narrative clue, but without ruining the overall silhouette. Use only brownish black ink and warm ivory paper, and create light and dark with dense crosshatching and fine dots. Give depth by expressing nearby railings and roofs clearly, and distant mountains and clouds with sparse lines. Don't fill the sky too tightly, but leave some space to maintain the stillness of an old scientific exploration illustration. Print only one completed scene without outer print borders, letters, numbers, signatures, logos, or watermarks.
