Great
3D feeling (I guess, the action scenes weren't actual 3D but those dancing people and self-asembling houses were?) + artistic treatment = awesome visuals. Nice music and great message (language is different, but love is one = make love not war etc.) too.
Actually people are right about putting two so different pieces of animation together in one movie - it would be also very good (even better) without the middle part with dancing stuff and "I love you" in 100 languages, but I suppose it is for some project or whatever. But the message was pretty clear without it too.
