Thoughts on Build

Hello everyone I was wondering if i could get some feedback on my build.

In a nutshell it is a primarily critical based build using iceshot. Essentially I wanted to seek out all notable crit nodes to maximize damage I also focused on quite a few life nodes as well to add some meat to the build. I decided that evasion was the way to go for defense making use of acrobatics and ondar's guile. I chose evasion because I didn't have many str nodes that could help meet the requirements for higher tier armors I thought though I am near a few 30 pt str nodes.

Question wise I want to know if i should scrap the evasion focus and move towards armor using iron reflexes? I also want to know if damage wise Im going to be ok i think i got enough of the crit nodes to give me a decent amount of crit chance and later on i am going to search for a high end harbinger bow and Im currently using maligaro's virtousity.

Here is the build as it is now:

Edited build after suggestions:

Come guys i see some views just share your thoughts with me.

The ammount of HP is ok'ish and Critchance should be more than fine - but Critchance without any Critmulti is not doing that much. I would trade the low Crtichance Nodes for the big Critmulti nodes.

Ok so less than 20% nodes in exchange for some big multi nodes. Also i think i should be ok with hp since its ice shot gives a good bit of cc. Thanks for your suggestions :).
