5 to 15-minute sketches from Bob Kato's Drawing club with subject Captain Kirk.
This is my first time experimenting with the new 3D brushes in Photoshop CS5. They add a lot of expression to the line, since it recognizes tilt and rotation, although somewhat crudely, and adds bristle behavior to the strokes.
The brush preview window at the upper left shows the orientation of the brush in real-time. You can adjust the bristle length, thickness, and stiffness.
