Rocks are thought to be alive by the Japanese gardeners who started all this. I can understand that - this one looks poised to greet all comers, and lend a hand if you need a perch for a minute or two.
Love the layout. Hate the caulk et the base of the front stone on the walk. Love the black monkey grass... But it needs something small and light green (like baby's tears) to contrast and pop the rich color. Right now it just blends into the mulch and almost disappears.
