I really like the shape which is a bit different from many Rain Tree bonsai. The main trunk and major leader are developing that characteristic rain tree warp. I have it planted on a rock but I haven't uncovered it yet.

Its biggest flaw is the lack of a root on the right or right-front. I'm going to try a suggestion that was offered - make a cut where I want the root, pack with root-tone, and bury. If this doesn't work, I'll probably try grafting and burying a small branch.
