my attempt at a walkthrough of my general process...
i generally use a flat (pallete kife) brush as seen here [link]
switching between opec and non-opec depending on desired effect
1. silhouette, rough out general shape of figure in solid black
2. block in value zones/ set pose
3. refining face, costume and body
4. defining light, cleaning edges, andcreating unique costume
5. rendering and final touches
feel free to ask any questions (=
i can make a video of my process if this does well
hopefully this is helpful to someone!
