I love Neon Genesis Evangelion and Adventure Time.
The original picture is the cover of the movie "Neon Genesis Evangelion: Death & Rebirth", drawn by Sadamoto Yoshiyuki.
I chose the characters more after the colors of the plugsuits and not after the personalities, since I think the characters actually haven't that much in common.
(Well, maybe except for Flame Princess and Asuka...
If you haven't watched NGE yet, you should try it. Although I believe not everyone will like it because of various aspects, it's still a glance worth! For me it's one of the most interesting and profound animes I've ever seen.
