People have stated their reasons for disliking the covers. So what if we don't like them?
They personally don't appeal to me because they look so... empty. Ayu doesn't blend well into the scenery. She's just standing their with the usual look on her face. The second cover looks like she's trying to fix her ear piece like she does when she's live.
The OBVIOUS Photoshop doesn't help anything either. She just doesn't look like herself. I think she's capable of much more.
If you like the covers, good. They're different and peacefully tropical which is what alot of people have been asking for for a while now.
