First i thought: "wow"
Then, after i've downloaded first Ayumix:

, each one of them has their advantages. In the first one i liked the flow, because anime that were chosen were really similar in terms of graphics and the people who edited them were already well known in here.
In this one one though the music is better and the video in most cases fits to it well ...both projects were kinda abstract, (who the hell knows nihongo to understand the lyrics) but it wasn't critic to enjoy both MEPs. Thanks!
Things which I really liked in this one:
Intro. Even if the 3D modeling wasn't perfect, we're all just fans, so even that attempt was fantastic! Special thanks from the CCS fan for letting Sakura using those magic cards ^_^ (great idea!!!)
Last Exile thing. There is no plot in it, but by that random-picking-scenes the person who put them together created something that i actually liked 'cause it fits the music.
Lucky Star / Haruhi part was perfect, i barely hold myself from laughing because of their attempt to pronounce some words

That was original
Segment H: LOVE IT!!!!!!! Beginning especially. I never saw something more... can't describe it. in two words: "perfect (music/video) fit"
10:43 -10:46 cutyyy good girl firing from the gun %)
And... wow, what am I seeing? people are actually dancing...?!!!! I'm surprised that that happened in the video...
Thanks Alex!
Overall
music: 4.8/5
MEP itself: 4.4/5
