Papaling,
Nice photography!
Somehow, for me, the music didn't fit the show... the second song was better than the first, though - more bold and lively.
This is unusual for me to say this but... with butterflies, you can get away with more pans and zooms - you can add more.
If you were to sync the slide timing very close to the music, the effect would be breathtaking.
I saw the common names and the species names, but what about if you added some points of interest as well - something unique and interesting about some of the butterflies...
I guess the main point is that the show lacks an "artistic" quality - it is more like looking at a butterfly book while listening to symphonic music in the background - nothing to "wow" the audience.
The end came rather abruptly for me.
You are off to a good start, now see if you can make it more romantically artistic...
Blessings, ~al
P.S. Although it is a very different type of show, here is one of my older ones that contains butterflies with the slides set very specifically to the music. (Butterflies and Grasshoppers!)...
