I've been watching your videos since the thetas covers (was friends with Hayden in high school, I think I found your channel through her) -- just wanted to say it's crazy how far you've come since then, your dances and the production all look so professional now and you're so confident, it's great and really inspiring. keep it up :D
I tried doing this with my sister, the movements are quick and we definitely were not synchronized. I wonder how much practice it took for the girls in the video to be synchronized, you have to be really energetic.
