The Living Dungeon

Another attempt using the new software(Which is still a pain working with). Sort of a living dungeon. Lots of tree roots and tendril like shapes. Would work well in greens or browns. Works well with the previous dark caverns set as it uses the same height and width so it should be pretty compatible and would give more variation to the tiles.
I like to think of it as a warren with one huge tree growing above it or an old cairn with roots grown into the crypts. But that's just my take on them.
