This photo was taken about 4 years ago when i won the "Landscape of the Year" in the City of West Covina California. I think this is how i started doing bonsai in my early years........
sorry but it looks like a pile of green balls. needs some variation in shapes. even elongated or eliptical shapes would add more contrast. please get rid of those pavers on the borders. how about some rocks instead? sorry to be harsh, but i would want the same honesty.
