Unless these practices are a minimum of 2 hours and over two months, if your group has over 5 people I still have doubts that everyone will be in sync and consistent. Hopefully y'all are practicing somewhere mirrored, crack down on people who don't feel like lipsyncing, and do some test records to get a better idea of if formations will look clean and organized when recorded and distancing.
Will have to agree that finalizing filming/shoot dates are a hassle in a group so whatever ends up being convenient enough for time and affordableness and keeps group tensions low to avoid ruining the mood sounds good. Then again I judge dancing/neatness far more than location/background as long as the lighting is reasonable but I do appreciate nice locations as long as it's not obvious that the effort put into getting to a nice location has drained everyone's energy and ends up cancelling out the nice background.
(If this is yet another Natsuiro cover I might scream since there are so many and whoever choreographed it has the strangest sense of rhythm. If not, kudos for going with the summer theme and something less common)
