I created a dungeon and overland style for Profantasy for two of this year's Annual styles. The sets are designed for use with Campaign Cartographer, but can be unpacked into the individual pngs for use in a vtt as well. The caveat is that they are part of the Annual Style, so you need to pay for a year's subscription to the Annual to get you hands on them. However that mean you'll get 12 sets of images rather than just these two tilesets.
The dungeon style is sized at 500px per square (yes, really!). It contains 63 objects and 10 textures. The objects contain some standards - chairs, tables, fallen rocks, beds, doors, windows barrels and such. There's also a collection of more unusual items - a stove, a well, a demonic idol, a corpse, a skeleton, a pile of treasure ... and a 1400px wide dragon skeleton. I find few things make a player stop and wonder more than a dragon skeleton they have to zoom out to see.
The tiling textures cover flagstones, cobbles, stone, dirt, grass, a tightly packed stone wall texture, wooden floor, wooden walls, water and lava.
and here's a quick map I knocked together with the items (feel free to use it for any non-commercial use):

The overland style is a different beast. This contains a collection of mountain icons as well as icons for towns, villages, hamlets and fortresses. It's based on the style I developed for the map of Rhune: Dawn of Twilight. The set contains 39 objects and 11 tiling textures - enough to put together a core overland map with terrain from swamp to desert.
The full annual subscription for the year is $40. You get these two sets, as well as 10 sets from other artists (I might have another this year, I don't know). I'm not on commission - these were work for hire contracts - so I don't get a percentage of sales. I just wanted to post a note if people were interested.
