Creating the Head Crest
Now I want to create the head crest. I know that I want the shape of the creature's head to be tall and suggest
the headdress of a bishop or a crown. This is to subconsciously reinforce the imposing, regal quality of the
figure. Follow these steps as I build up the head crest.
Use the Move brush to pull the top of the head up ( Figure 3-31 ) . The shape I am going for should suggest
a crown or a bishop's hat ( Figure 3-32 ) .
