Is this bitcoin storage safe?

[And1]

1. I've set up Tails LiveCD on USB together with Truecrypt container consisting Armory and all needed *.deb packages.
2. Installed Armory.
3. Created new wallet named "Offline" and also created it's watch-only version. Both are crypted.
4. Imported watch-only wallet into online Armory.
5. OFFLINE WALLET NEVER TOUCHED ONLINE SYSTEM UNCRYPTED, its placed on Tails live USB in Truecrypt container.

Did i forget about something? Is this offline wallet now really safe? I feel strange my wallet never went online at all. Is it really good?

Forgot - i made copy of "Offline" wallet and stored it inside another TrueCrypt container, gonna make multiple copies. Also going to print paper copies.
