Been working on a similar thing recently, but this looks fantastic It looks like you're using some kind of perlin noise, one idea I had (probably been done a million times before) is rather than using the "height" of the noise to decide on a tile, you could have it decide on a biome, which itself has a list of tile types with a weighted random choice of which one it picks; so you're forest areas can still be populated with grass for example, but tree's are more common.
