Last November I stumbled on Miska Fredman‘s Instagram account and noticed he was drawing maps with #Mapvember. I got hooked. I even draw some maps myself too and Aki wrote about automated map generation.
Since then Miska has gone on Patreon and is drawing maps in addition to his job as the founder of Ironspine (Finnish rpg publisher). It seems like his map drawing has really paid off. At the end of August he published a neat booklet called A Dozen Dungeons (link to DriveThruRPG).
