Comment my houngan build, 500BP Voodoo Mage/Face Options

[Professeur]

Alright, I'm not so good at doing mages in general, but for this game I decided to go for a Wakyambi Houngan. Now I've heard a lot of things about posession being broken in general, and I'm not looking for any game-breaking power here, just a nice, balanced character. I'm turning to the dumpshock community for input on this one.

Here are the rules
CHAx2 Free Contacts
Skill group breaking allowed
500BP, 250BP on attributes max.

Here's my first draft, comment away.
