Icespear Totem Player needs help

I am looking for someone who take a look at my build (items, passives etc.) and give me a feedback, what i have to improve or change. I dont get it working, either i lack in defense or offense or both and i dont know what i have to do to get a good working Charakter..

Ofc I will give my Pob and any Information needed! I am working atm so not able to post it right now
