Deadwood Texture Experiment
High definition of the wood grain can be achieved a few different. Ways:
- Peeling portions of the heart-wood with pliers 
- Torch and wire brush 
- Bead blast 
What I propose is experiment on is to use a radial wire-brush as an easier means than bead blast.
The tree specimen used is a mature Japanese Boxwood
