I want you to create a top-down map (no angles) of a city sewer

I want you to create a top-down map (no angles) of a city sewer. It is an underground labyrinth of dark, damp tunnels, with old brick walls covered in moss and slime. The narrow corridors are lit only by dim, scattered lights, with shadows cast by the pipes that intertwine along the ceiling and walls. This map will be used for tabletop RPG games on the Roll20 and Foundry platforms. (Make it with anime graphics). (The map must be very large.)
