An observation on subdivision.
It seems that subdivision by 1/2, is not very compatible with the topology of AM. There are better results by 1/3.
For the follow examples, I use the SplitPatch plugin that use subdivision by 1/2.(thank you Yoda for all yours plugins!)
The subdivision by 1/3 has been done by hand.


Some hooks can cause problems. (because it is not possible to stick more than three hooks per segments)
So prefer to use the third solution.
