Great pics! Very nicely done. As to everyones moss question try using pieces of sandstone in the areas where you want moss to grow with dampness and shade. The sandstones surface is the ideal place to grow. Just transplant a piece of moss that is growing onto the surface and watch it grow just like a chia pet lol.. the sandstone surface is just like that of a clay paver or a clay head. Granite stone will grow moss but it will take a lot longer than sandstone. However the key is shade and moisture.
