I've wired the Carpinus.
It's not finished, but there are some strong curves, that injured the bark. So I waiting a little bit.
And some skeches from the future.
In this skech man can see the problematic points. The branches No.1., and 2. growing in wrong direction. The angle of branch No.3. is not so good. And with the red arrow signed point on the right side is also a big problem. Here the two branches or trunks growing first wide, and after close to each other, and again wide.
On this skech man can see, what is my idea. The two branches make close paralell, the bigger branch or trunk curve to the first branch. With this movement can be harmonic the crown.
