8. For the mouth's area, I need more CVs to get the shape out. So I insert isoparms and start to pull the CVs around the mouth. (Figure 8)

(Figure 8)

9. Then I insert more isoparm to the head and pull the CVs, the creature's head start to form. I select the left head, use duplicate instance and mirror it to the right. With duplicate instance, when I pull CVs or insert isoparms of left side head, the right side will follow. This will help me to visualize the complete head of the creature. (Figure 9)

(Figure 9)

10. This is how it looks like. (Figure 10)

(Figure 10)

11. The horn is deformed from a NURBS circle. Then put them to the location. (Figure 11)

(Figure 11)

12. Insert more isoparms to the neck area, pull CVs to get the shape of figure 12. (Figure 12)

(Figure 12)

13. O.K, now I delete the right side head. Then I mirror the left head to right again. This time, instead of duplicate instance, turn on copy in the duplicate options box. (Figure 13)
    At this stage, I add more isoparm at the nose part so that the CVs allow me to create noise trail.

(Figure 13)

14. Now zoom closely to the edge of the left and right head. Pick mask Hull and CVs. Turn on X-ray and back face culling from shading menu, located on top left side of view port.  You will see the CVs of both sides is not meet together. This will cause seam to show up where two surfaces meet. We will fix this manually. Hold down V for snap to point. Select 1 CVs, move and snap them to the CVs in the opposite. Do this to all of the edge. (Figure 14)
(Figure 14)

15. Then I attach the surfaces into 1 surface. Then rebuild surface with the CVs turn on in the option box. Click Rebuild. The head is done!
