I'm currently stuck in the "Creating Silenus's Head" portion of the book. The steps provided were to create a cylinder ( 8 sub axis, 1 sub height) and a sphere (8 sub axis, 8 sub height); scale them into position, delete all but the top bit of the sphere; then snap the points of the 'cap' of the sphere onto the cylinder, and merge the vertices to complete the shape. All OK so far.

Now, it instructs you to move vertices around to match the face, in front and side view. I found this somewhat difficult, considering the amount of vertices I had to work with. In the book illustration, there seem to be more horizontal subdivisions than I had in my model. Did I miss something? Or is it assumed that the reader knows how to horizontally subdivide a non-primitive polygon? If the latter is true, I would like to know what method I should use.

Here are some screenshots:
