The recipe is the style, not the picture. Put your own subject in and the highlighted part of the prompt changes.

Prompt

A city panorama drawn entirely in fine uniform blue pen on white paper: dense towers, construction cranes, an elevated road and thousands of small windows, all described with thin even line and no tone or fill anywhere. Obsessive detail at consistent line weight, so the skyline reads as a pale blue haze from a distance. A few faint pencil guide lines left visible at the edges.
