... Oh. The new S-Rares are made with matching costumes. They didn't do that last round. I like it, actually. It also shows us their image colors. (Which I find somewhat hard to figure out, at times, since I almost always default to the main color of their type; AKA blue, orange/yellow, or pink. Mika's hot pink makes sense, I like Miku in red... And Kirari can't decide. XD I also like how she has all the others in her hair.
Kirari, you so genki. X3
Specific commentary:
Ranko's hairstyle is really cute on her. Not that I want to see it again, necessarily, but it's a refreshing change.
Um... Miku... You're 15. Stop that.
Kirari! You're so cute~ But extremely colorful. I can't tell what they were going for with her hair. Are those macaroons...? The chibi faces are cute, though.
Well... Mika, that's an interesting pose, but nothing sticks out in your card to me, other than that the art is significantly better than the upgrade to your original card.
Uzuki! I'm biased towards her, but she's ADORABLE here! Also, it's nice to see a new stage outfit for her. Not that the CGirls have many stage outfits in general, individually at least, but it's nice. That's a nice hat, too, if I could see it better. (How does it stay on her head, if it's all the way back there...?)
