there is a little mountain on the left side. is it suppose to put the rock in between the soil so the slope wouldn't fell off? is the moss mounted onto the rock or driftwood?
so, the soil layer has to be very thick on top of the rock? otherwise, how you can put the plant into the little mountain?
this is gorgerous, amazing natural picture.
just try to learn more. don't laugh at me to learn something so difficult and impossible to reach.
