I love Vocaloid! But I like anime too...just...not any of the ones you listed. :P
Currently I'm watching Red Garden and Princess Jellyfish. Both of them are really good, but they're completely different lol.
My favourite anime is Haibane Renmei. It's gorgeous. Beautiful art, music, characters, storyline... I could seriously go on about how much I love this show.
The second one be Angel's Egg. It's more of a surrealist artistic movie, but it's also really beautiful.
Some others that I like are Di Gi Charat, Michiko to Hatchin, Axis Powers Hetalia, and Sayonara Zetsubou Sensei.
There are a few others I like too, but since some of them have content I'm not exactly sure are too kid friendly, I won't list them here.
