Big hornbeam doing good

I bought this hornbeam at the Ginkgo Bonsai Center in 2007. The first picture is how it looked then. Last spring it was pruned back pretty hard and potted in the largest container I had available.
This year it is really thriving and growing well. It is a big tree, about 90 cm including the pott.
This is how it looked when I bought it.
I'm very happy about this tree and it is nice to work with some decent starter material. I prune back the new growth asap.
