It's great to receive feedback, very encouraging.
The dance videos (on http://www.rarolens.com) are from an annual cultural competition we have on Rarotonga. The items are between 5 and 7 minutes long and I always edit them down to about one-and-a-half minutes so they act as trailers for the Ministry of Cultural Development DVDs that have the entire competition.
I only use one camera but try to get a variety of shots knowing that I'm going to edit down. I then select a suitable segment of music from the item and make the shots fit in.
Glad you liked them.
