I am the Game Master for a weekly tabletop campaign. Each week I create all of the battle-maps that I run encounters on, as well as the city maps that the players visit and any environments that I need to visualize to the players. I have on occasion made up to 6 different maps within a week, many of which were designed around using a virtual tabletop's lighting engine to customize visibility. Below you can find examples of the maps I've designed.

All maps here were made using the map-making tools at inkarnate.com
