On the first photo is tree (Quercus ilex – Holm oak) before work on deadwood. Secondary trunk, on right side was too massive, with a strait cut and not interesting. So the option was to improve it, make it optically lighter by making deadwood. Also on main trunk two holes  are  connected and enlarged now.

This is Holm oak (Quercus ilex) collected few months ago. Quercus ilex is domestic plant here. This tree is the first Evergreen oak that that we like and decided to collect. Nebari is pretty natural. Tree looks interesting from few angles.
Here are two photos after collecting.

New sprouts in spring. Next winter we will shape the tree, now we are just considering options. What to do with lowest and the thickest branch; cut it entirely off and make a one more hole, or leave it and threat it as secondary trunk … we will see!

Small lizard lives in one hole.
