Today I made few shots of this little tree. It was wired and styled in December last year and you can find his short history in pictures in post here. Leaves are now emerging and are small yet. Structure of the crown can be still visible for a while, but it will change in about one week. Top of the soil was covered with moss but it did not made it during the winter. I have to apply new moss in next few days. Pot is not final and is too big. Tree is vigorous so it can handle smaller pot without problems. May be next season. Last picture is one of possible future fronts. But with naturalistic bonsai you should have nice tree from more sides. I'm sure with this fraxinus this is the case.
