TBH, I think this is a bit rushed...
You should definetley put 3 DMG slots in all attacks, and start 3 slotting powers more.
eg: Aim - 3 RCH instead of just 2
Snow Storm - 3 slows
I believe it is always best to get powers to their full potential, instead of trying to do everything a little bit.
You should also do a build up to lv 40.
Snow storm doesn't need 3 slows. The slow on it is awesom enough as it is and the enhances can easily be spent elsewhere. I have a lvl 40 Ice/ice and have not slotted a single slow in any powers, anyone who's fought me in PvP would be able to tell you it doesn't need slows in it.
You may want to reconsider firebreath though. The animation on it is very long and needs you to be in close to be effective, normally meaning you're dead by the time the animation finishes 
Ont thing you haven't specified is if it's a solo or team build and if you want to PvP with it?
I have a level 43 fire/thermal and level 42 ice/ice so if you let me know what it's intended use is, I'll give you some tips.
Your hurting my eyes with that font! 
Slap some accuracies into infridigate, just 2accuracy.
Take frostwork, pick up stamina later.
I'm generally a hurdle over health guy.
For my first 20 levels planned build....
