I uploaded my first two animations on ShareCg.  I also found a great place for mimic sound files
without music.

www.librivox.org has free public domain audio books anyone can use.  You just have to make sure the voice matches your given figure.  Even if you don't use books for Daz they are still nice to listen too.

Theres still that problem with key framing the head motions but its workable.
Hope you enjoy it.
