Did a little 3D modeling this is the result :p.

The head looks fine by me, the cloth = crap. Will try to find a solution for this.
Problems I faced with this cloth:

Somtimes the cloth just stops moving.

Solution: the cloth has something called: random acceleration. This makes sure the cloth is always moving (a little).

The cloth moves slow

There are too much calculation being done.
Solution: make the cloth out of less polygons.
