Wow. I'm really impressed!
As you all said they did a good job on so many levels here.
As regards ayu, she did a wonderful job vocally wise. I was first under the impression that her voice was live corrected but the few off-key parts prove me wrong. She hit some notes I thought she wouldn't almost effortlessly.
Of course there is room for improvement, more control, less shouting, better breathing. But she really delivered (no pun here
). Keep on the good work.
As regards her look, I think she gained more weight after CDL. That could explain the swollen face. Or some medical treatment. I hope it's this + the pregnancy and not some fillers that she really doesn't need...
