Interesting, will the rest of the lyrics be added over the existing 2min track or will it take place after. Currently it seems that the existing track is leading into a longer lyrical section which would move at 1.5-2x speed before then returning to the original pace. It may be nice to try to fit two quatrains with a short buffer at normal speed between them before moving to a short final that is a repeat of the current lyrics but restated differently. This would lead to a total time between 4-5min.

Do you have a raw text of the verses so we could look them over? So far I really like the current lyrics and the theme that it builds. I understand if you are pressed for time and do not want to expand the scope of this work. However, I do believe that it could be turned into something larger if the suggestions above are followed. I am heading out of town and thus packing tomorrow so I will not be able to help much more until next week. If you wanted to make it longer in the future and need additional lyrics be sure to post and I can have some written up. I can also call a few artists and a music director to get some opinions.

Also just to clear up anything, I do not nor ever have made music, I am just an audiophile so you can take my opinions cum grano salis.
