This is a 3d model I made of professor Genki from the video game saints row. I made this model so that I could use Pepakura and turn it into a real head.

Step 1: The Head

Firstly place a sphere then another one just next to it. Then combine the two spheres. Finally use the fillet tool on the line in between the two sphere until it looks like so.

Step 2: Facial Features

Now the facial features, firstly place a cube in front of the spheres and draw the facial features on. The mouth, the noses and finally the glasses. Next extend the cube upwards and draw on two ears. Now delete the square, extrude the mouth, nose and move back the glasses. Finally move the ears back, rotate them into place and draw a circle at the bottom and extrude to make it into a head.

Step 3: 3d Model and Pumpkin

And now the steps for the pumpkin.
Draw a large circle at the bottom of the head and extrude it almost all the way through. Then extrude the mouth, nose and mouth.
