Billy here: Micael: I WISH those were my trees. The forest is John Naka's Goshin. The others are from the National Bonsai Garden at the National Arboretum in DC. I had a few very nice ones, but nothing even close to the caliber of those works.
My best, a 42" tall straight trunk, 6" diam "lightning-struck" topped Hollywood juniper was given to Geo Yamaguchi when I gave up my collect. Saw it for sale at his nursery years later with a hefty $1200 price tag on it. Very proud moment. Hope it found a nice home.
I like your "trajectory." Bonsai opens a lot of doors once the aesthetic sinks in.
