What do you think of my Frost Mage Build?

I've still got a way to go as I'm only in my 50's, but this is what I'm building towards.

I took advantage of the forced respec and changed some things, and moved in this direction.

I'm open to any comment, if you don't like it please point out why.

I originally thought 'Brain Freeze' sounded silly, but after trying it I think it's pretty cool - so I'm open to new ideas.
