Heres is the Excellent Video Training Digital Sketching For Graphic Artist and Game Developers
Learning to sketch confident linework with a stylus is hard. Even for seasoned traditional artists. To help simplify this intimidating subject, I've broken down 'sketching' into independent skills. This collection bundles all 5 of these series together, concluding with "Weapon Design" – a Portfolio Builder to test your skills. Each of these series offers assignments and drills, ranging from simple to complex. To follow along with the videos, I've also included a set of natural media custom brushes for Photoshop.
