The art are really cool and inspiring for making Regional Map.
I found one small drawback :
No swamp Tiles for Mork Borg or other Sludgy Map :'(
I will do an update eventually so all recommendations for new tiles are appreciated!
The new tiles that I could think in addition right now with my current dark fantasy campaign are : cemetery, dead tree, monastery, pentacle shape, cross shape, volcano
Could be really cool also to be able to make local map like town or even dungeon with the same kind of art. I don't mind paying again for that.
