The Character Portrait: Sculpting the Alien Mystic - ZBrush Creature Design: Creating Dynamic Concept Imagery for Film and Games - page 66

One of the first steps to a good design is sketching ideas. You should always sketch in some form, such as a
ZBrush doodle or even a series of thumbnails on a piece of paper at your desk. This allows you to work out
ideas and poses quickly so that you don't waste time at the computer. Figure 2-4 shows a finished image and
the original sketches. Notice that the sketches can be very rough. The idea is to work out the rough ideas on
paper, where you can think quickly and are not bogged down in technical considerations.
Figure 2-4: Here you can see my Centipede Magus illustration next to the original thumbnail. The ideation
sketch need not be elaborate. A simple rough figure will do to work out big ideas.
