Just a bunch of screenshots (from Tiled) of new tilemaps we created using OpenGameArt artwork (attributions and source links). We'll bundle these ready-to-use tilesets and example maps with TilemapKit. For us it was mainly an exercise to verify that TilemapKit rendering works correctly with a variety of tilesets and map settings.
Did you make these with tiled?
#4 is with the grassland tileset from opengameart, ne?
Is the last one also from some freely available tileset?
Yes, they were all made with Tiled and I believe except for one (#7) they are all OpenGameArt tiles.
I posted a list of OGA tilesets here where you should find all of the tilesets used in the above screenshots: http://forum.mapeditor.org/t/best-orthogonal-isometric-and-hexagonal-tilesets-on-opengameart-org/506
