I really like how she sounds! Though it's probably because it's Miku and she was mixed well. I don't know if I can really judge her accent without hearing an acapella sample, but even then, I kinda like it anyway. She's so cute. I'm looking forward to hearing what the mandarin-speaking community thinks of it, though. Back when Miku V3 eng came out we were all ragging on her accent for being too Japanese.
