Figures from scratch? You, sir, are a brave and talented man for taking on that task! I salute your efforts in advance and will eagerly await your progress pix on this project.
I'm more of a figure modeller than anything else, and done some heavy conversions before.
I love seeing Vlad's in-progress sculpts for the Bravo-6 figures, and asked him if he could post a photo of the armature he uses, which he very kindly did, so thought I'd try it the same way.
Unlikely I'll be sculpting any heads......
