Overall Positives: Omg, this was just so adorable. I love this kind of dichotomy of the 2 cute voices and the 2 more mature voices. I'm going to be talking out of my ass from here on out because I haven't heard this original song, but I think I'm going to do so after this!
Timing: I don't know this song that well, but overall, it sounds pretty good.
Volume: Nothing that I would complain though, I hear a lot of the cute voices in the
Overall Sound: you mature girls sounded... fuzzy? Which is weird because Liana, I know you haev a pretty good mic. Oh, I just read the description where you commented on it. That could explain why that's all I hear is the cute voices in the group parts because they sound pretty clear.
Overall Vocals: *-* good. So cute.
Other: All this is not related to your dub XD Wtf is up with Tsunku doing a whole bunch of repeating nonsense in this song and the Puccimoni song? I think it's time for Tsunku to get a dictionary because I'm starting to think I have a bigger Japanese vocabulary than Tsunku does. Also, Tsunku sounds really creepy in here.
I just listened to the original, and I don't think the instrumental you have there is really that bad. The original sounds like it's... lacking on the instrumentation.
