The Eva AMV focuses on Asuka, as the other Eva AMV I did was of the whole series, and mainly focuses on Shinji and also Rei. Also in the Toxic music video Britney is wearing all red and one could (I might) argue that she's channeling Asuka's energy riding on the back of a red Ducati.
The Bleach AMV is mainly because Bleach was on of the main anime I was watching at a period of time when I was watching AMVs in my youth, the 240p and hardcoded subs in this version is on purpose because it's probably closer to what I would have seen on youtube in 2007 — though I don't think the anime was as far as the Heuco Mundo arc by then, anyway...
And MGS3 to the Dusty Springfield song because it just...fits so perfectly. I later found out that the song was written in 1964, the year the story for MGS3 takes place. It makes me think of an old James Bond or spy movie trailer.
Let me know what you think!
