I like it!!
In general: starting to like Chinese elms more and more, the little leaves are great for the general appearance/ratio trunk-leaves of a bonsai.
Add to that their lust to grow, and no real problems with pot culture.. I love the species, and feel everyone should have one or more elms. Great starter trees too. It is just sad that mass production makes this an ignored species.
The leaves on this are now only a few mm. They will become larger of course as the branch extends. But imagin this 2-3 times as tall and as wide as the pot, with 2mm leaves...
