Its fine tho
You should get someone else in your group to get Icy talons 20% haste (enhance shammy or another frost dk) so that you can save 6 talent points
you dont need 2 points in icy reach just use taunt to pull
A rough estimate of your build fixed - http://www.wowhead.com/?talent#j0EMZhxx0AbI0czisst0x
What I personally suggest - http://www.wowhead.com/?talent#j0EGZhxx0AbIoc0iost0x

Icy reach is commonly skipped for a tanking specc, it's mainly for pvp overall.
Acclimation is highly situational and has a poor uptime/procc chance so it's also commonly skipped.
Lichborn has been changed since pre-3.1, it's now more of a Will of the forsaken ability, making it again, more of a pvp ability (to break CC)
Hungering Cold is also commonly regarded as a PvP ability since it does nothing on bosses (but apply FF) and is highly situational for trash/5mans.
You're also loosing out on some great tps by not taking Killing machine, Chill of the grave and deathchill (good for howling blast on trash etc.)
You've also missed Annihilation which is one of the key abilities in Frost (since frost focuses on Obliterate)
Here's some modifications to your build:

(the points in morbidity can be moved to, say, SoB/Epidemic)
