I think they should ask the dancers to do all the acrobatics behind him until 2:06. Or, better yet, have them dance an older fashioned/social(?) dance before 2:06, and again, behind him. Aside from that, I think I can hear another voice besides Cezar's when he sings, if that's indeed the case they should make said singer more visible and possibly give her a ball gown while letting her sing a "bit" to the side from Cezar himself, though, I guess it's too late for that.
I also hope the dancers, especially the girl in the light green top, will wear something more elegant, perhaps a bit similar to what the dancer at the near end of the video is wearing? Maybe they could have him be raised up on that... podium thing(?) the first time he hits the high note along with making the laps become redder if they want to have the dancers do their dancing and acrobatics in front of him?
Also, I'm not sure why there's so much lightning in the beginning...
Oh well. It's bound to look better (hopefully) with different camera angles on the 16th.
