I’m making up the process as I go. Using photo reference transfered with graphite paper, I set in the deep crevices. Bark is rough, so I have to avoid the temptation to smooth things out. Next I textured the surface with a small u shaped gouge. Now I will come in and create intermediate sized crevices and clean up the two vines. That will be as far as I can go with carving. After that will be painting.
