Awesome work dhama...you will be uploading this to free stuff..correct?...would you consider exporting this as a  more common format, .obj or .3ds.
Its on of the best I've seen and for a while thereI was on a mill hunt..gave up the project as I had no time to model it and was wasting too much time looking for one..will try my project in Bryce if need be but it was originally gonna be an Imagine3D project anomation test...dunno if my idea will work in ZBryce is why I ask for more eventual formats....well done tho

 

Once in a while I look around,
I see a sound
and try to write it down
Sometimes they come out very soft
Tinkling light sound
The Sun comes up again
