Cold + (Fire or Lightning) Witch build

Hey guys.

I just came up with this build, I didn't use endless hours in building it and I've just started playing Path of Exile today.
The core damage will be dealt by cold damage, but as a exampel I've added some points into fire spelled damage (could aswel have been lightning damage, doesn't really matter), as I feel u need to have atleast 2 types of damage as a Witch, cuz many minions are immune to your core damage.

Tell me your thoughts guys, I'm level 12 so far and havn't spent a single talent-point yet, as I don't wanna make any dramatical mistakes from the beginning :)
