I've just created a Chainmail brushes pack for Photoshop. The mail parts of this character are realised entirely using these brushes. I'm happy with the result as the brushes not only saves a LOT of time, but also provide a highly detailed result.
The knight is typical of the First Crusade, Norman style, bearing the Hauteville family's coat of arms on the shield, from Sicily.
The pack is available here! artstn.co/m/Wm9g
