Yes, that's exactly what I thought. While this tileset looks almost completed, it really isn't though. There should be more colors, the vine looks horrible, the background should be changed, the middle part of ground doesn't tile (if I remember well), elemental and space parts could be added and a lot of other tiles. Overally, if you'd delete the tiles which we should edit, probably the only part left would be an empty tile at the upper left corner.
