Great work! This thing has an economy of words that is wonderful. For the swashbuckler we get "Malnourished human in a rusty breastplate, fancy moustache." That is everything the GM needs to know to make this character engaging and interesting. Similar examples abound.
The layout is simple and clear. 10 minutes of prep and you could run this. It uses the Necrotic Gnome style, which works well here. There's a few places where I might move the monsters to the beginning of the key to make them more obvious to the GM (and players) but that's a nitpick.
There's plenty here for a night of fun and shenanigans. Very well put together, very atmospheric and evocative. And the artwork is great.
Hope we see more from you!
