Is that rizla packet there for scale or what?
I’ve thought about carving down to soil level, to create hollows akin to those on your inspiration tree, but thought that the deadwood will rot too quickly because it extends in to the soil, is that not a problem then?
Have you ever been to Blenheim Palace by the way? The Oaks in the estate grounds are crazy. Got to be at least 20 (at a very conservative guess) that are over 800 and all are obviously so.
Not my pictures but here are a couple for a bit of a flavour for you
