Some of my son's work in 3d program

Here is a guy that my son has been working on in a 3d program. He is pretty good at this stuff, one time he did a 3d model online of his room, right down the the wood grain on his desk, the screen saver on his computer and even the keys on the keyboard!
From what I can tell he starts off with just an oval with lots of lines around it, unless he is using a different program now.
He is also pretty good at drawing anime.
