Aura choreography

I have now started to create the choreography for the 'Aura' music video.  I have now enlisted the help of my schools dance teacher and we are now starting to create a dance  We have also found a video on YouTube and are using that as a starting point.

 I have tried to contact the remember the feeling dance group on their YouTube channel.  Here is my short post 'hi, I'm trying to create a music video for the song Aura and was wondering if I could use this choreography for my video.  I really love what you have done and I would love to credit you.  thanks.' 

I have received ':)' from the company and have understood this to be a yes.
