Hi.

Without further ado

How can i make realistic moss? I have tried and all i could do was this: http://i.imgur.com/A8d3zA6.png http://i.imgur.com/3hVA0n6.png http://i.imgur.com/KyqOXMq.png
If you have any ideas or know how to make moss in blender please tell me how.

They look pretty good. Only comment I have is that they look too clean. A real patch of moss tends to look more patchy; brown stems showing here and there, with more color variation:
