Well, here are pics of one of the human models I made. This is female figure made in Gmax. It has a polygon count that can equal a plane's poly count.
As you can notice, the ears are not there. The ears are one of the hardest things to make. Especially if you are planning to apply the Meshsmooth modifier to it.
The model has been made entirely with Gmax.
The body has been made out of a simple box (low-poly modeling) that has been extruded on certain places to make the arms and legs.
The head has also been made out of a simple box. It was later attached to the body so that it will make smooth, seamless model. Then I added the Meshsmooth modifier to give it the fememine figure.
The shirt was made out of a cylinder and the pants was made out of a box as usual.
There is a website that can teach you how to do this.
