The Dragon's Quest (new version)

Hi all.

Have recently added a whole new section to my piece "The Dragon's Quest".

Was trying to create a more exciting climax, by using call and response, with rapid changes in orchestral texture and modal colour. 
The new material starts at 5'42", then mixes back into the old ending at 8'14".

I'm still working on the score: so loads of enharmonic spelling errors remain. The pentatonic sections require Gbs instead of F#s, etc...

Interested to hear what mental images it conjures up?

My vibraphone part is going out of range at the top: so need some ideas on how to fix that?

A celesta could cover all the notes; but may not be loud enough against the other instruments playing?
