The second image is what I'm going for for the extra fine lumpities that moss has that give it the really soft looking texture. It seems that moss is a layer of fine lumps on top of larger lumps.
The third image is the second image added to a less frequent noise. However the large lumps do not match the color and are way to uniform. If I can combine this noise with the first worley noise, then add the fine noise on top, that should be a great combination.
