That is the tech demo you want. When Zelda U releases, it will have a heavily anime-inspired style, lotta art, lotta colors, very flashy, and probably nonsensical. For some reason I have a feeling the tech demo will look nothing like how the game actually does release.
Truthfully, I don't want it to look like it. Zelda's tend to have a very specific theme when it comes to art. I hope it expands upon the style from Skyward Sword. That's my opinion so don't bite my head off for it. I mean, I used to appreciate Zelda games for the music and gameplay, now the art is really getting me hooked.
