I'd move it about 3/4'' to the left, drop left side about 1/4'', turn the tree about 5-10 degrees of current front (by container edge not photo) bringing the right side forward and left side a bit back. Remove heavy branch in upper front-left canopy and fill out lower right branch about another 1/2-1'' in the middle keeping the front edge more thin. Apex may need to come down a 1/2" and be rebuilt but can't tell from photo. Silhouette is good but a little even on both sides. Container size could be narrowed width wise and height could come down by half for a show, then put back into something deeper. This would allow for a nice stand under the bonsai in a box display. Keeping the heavy pot and not using a stand would make the canopy (and tree) appear smaller. A dark blue oval may be good too but I'm biased.
That's what I'd do. Just a shift to left would work for current style.
