I usually like to just lurk and keep to myself but maybe just this once, I'll pipe up....
I really like the displays you've been posting. Apart from compositional issues like balance and scale, I've been drawn to the ideas of "the stories" and "the ideas" being that the bonsai artists are trying to convey.
I'm not sure what the accent is... It looks like some kind of figurine, but I can't quite see enough detail. For me, this display is evocative of ikebana: In traditional, Japanese flower arranging, the three elements depicted are usually heaven, earth and man in a harmonious arrangement. For me, the scroll evokes heaven; the bonsai, earth; and the figurine, man (I'm just guessing at what the figure is).
