The impression of my initial glance struck me with the following thoughts...

1. You seem to have three trees of the same diameter.

Suggestion: Allow to grow out freely to varying degrees, respectively, so that you have a clear primary, secondary, tertiary... I would tend to do it left=#2, middle = #1, right= #3.

You could change the status of left and center since the left is growing out in the "open" and would receive better resources...

2. Another optional thought- your accent tree to the middle maintree- placing it behind the larger trunk might give better perspective- but the way you did it is perfectly fine!

3. Add smaller trees to the back for depth/perspective. This species roots well from cuttings... As you trim, just do it then - then you know you'll get similar characteristics...

4. To further work the perspective, raise the right hand groups onto slight hillocks. Smaller trees can be behind these mounds to "hide" them giving a sense of trees in the distance.

Be sure to post a picture in a year or so to update us!
