Having looked through all Risako's blog photos and as a photographer, I honestly can't see that her pictures are different from any other random instagrammer. The "dreamy style" you reference is just a simple -10 or -20 Saturation. Also the focus is terrible, but if she's using a phone to take them then that's understandable. There's a girl in AKB who has a real camera and real photographic knowledge, called Takeuchi Miyu. Her G+ has some good examples of her work, mostly landscapes. Her self-portraits do suck as well though.
@ BerryZ LoLiPoP > thanks for the info about the original song.
The original "CAT'S EYE" is by ANRI. It was the first opening theme to the CAT'S EYE anime.
I like the girls' cover of it. It's a nice modern version :) The adding in of the rap was a nice touch, IMO. Though I feel it's auto tuned to death. It sounded nice in some parts but I think if they just kept there voices normal it'd be nicer. I still really like this song a lot :)
