Cancelled Plan on filming Tomorrow, Tuesday 29th

As I do not have much filming left to do till the production of my music video is finished, I am planning on filming tomorrow of the shots of just my main character in it before filming all my characters together for the rest of my music video. I was going to film my main character walking on the path in the park for the first verse, also for one of the choruses, I would need to film her alone in a field and of her spinning around. However, I have spoken to Ellie about tomorrow and she has said that she would not be available for tomorrow's filming session as she would be busy. I have asked her if she could do filming on Sunday 4th December and she said that she is free. I have left filming for Sunday as me and Ellie would be busy for the whole of this week and also Sunday is when we would have more time and could start early on filming to get more done. There are only few more parts of the music video where Ellie as my main character is on her own in a shot and it is at the start and end of my music video. These shots are of her sitting down on a chair with the spotlight shining on would be easier to film in the Drama Hall as Ellie is always in after school and the Hall is free to use after school. I am hoping to film these shots in the Drama Hall next week and after filming this footage, I would only need the filming of all my characters together to finish my filming of my music video.
