She's making the duck face more, and she looks like she's lost some weight. The crying part of Love Song I swear she looks like this one Drag Queen... No offense meant to Ayu (more so because I do happen to love the look of that particular drag queen..), but they have the same really high cheekbones that looked way too exaggerated for me n that scene..
That and there are lip glosses and lip sticks MEANT to make your lips look more plump. I think she's just using them a lot lately.
