Looks amazing! Love the extra details you added to the walls!

I would also advocate to you to try and larger brush! I am not sure where you are located but here in the states, Home Depot has small and large, pure bristle paint brushes for under $2 each in their paint department (plain wood handles). They are cheap for a reason but make excellent dry brush brushes. I notice if I use too small a brush, its hard to dry brush off enough paint as well as retain enough to get the full effect. For these bigger terrain pieces, a bigger brush makes it a lot easier! These are the small ones:

@Kacee Gresham Thingiverse is the best place for free monster mini files! I started printing these in FDM but earlier this year graduated to resin printing my miniatures. The quality jump is amazing, but FDM can still get the job done. If you want to pay a few bucks for higher quality miniatures, MyMiniFactory is the best in my opinion. I also use miniatures from other board games (Frostgrave, Runewars, Reaper Miniatures etc.) as taking liberty from the official artwork yields some REALLY awesome alternatives. https://www.thingiverse.com/search?q=Gloomhaven&type=things&sort=relevant Hope that helps you get started!

@Talisman Sabre Terrain Can confirm, this happened to the one I just pulled off the printer. It's not a terrible mess though! I was able to snip away and touch-sand those spots and you can't even tell.
