Logo

I really love the way the numbers fade into the distance; I know before it looked blocky, but now it's a very subtle, nice touch. I do notice that Deja Vu is a bit hard to read, maybe you could do it in a different color? Overall, perhaps the design could have more color, so it doesn't seem like we are focusing on Miku, though of course the blue-green is the color we associate with technology as well... Maybe you could color the sparkles and notes different colors. I would add a sparkle or note somewhere above VOCALOID, since that area doesn't ahve anything in it right now.
Overall, it's very simple and clean, which is good for a logo, but I think a few additions could make it more interesting.
