Kujira no Kora wa Sajou ni Utau (Children of the Whales)
An oddly animated show with a blend of traditional anime visuals and rich watercolor-esque backgrounds. The characters are diverse and well-balanced, and the use of 3D visual effects are minimal and barely noticeable. The story seems quick-footed and it has a nice momentum so far, hinting just enough at a wider perspective to keep you interested without giving away too much. Reminiscent of Suisei no Gargantia.
Kino no Tabi (The Beautiful World)
Sometimes distracting with quick swaps between 3D and 2D, and overall plain-looking. Story- and content-wise, it seems promising with each episode serving as one entire arc. Most things are explained as the main character learns about them, so there's no annoying omniscient narrator - just dialogue between Kino and her bike. I do particularly like the bike as a character, since it has no comical reactions or expressions whatsoever, and relies on voice only to elaborate his feelings. Has a Princess Principal feel to it, but far less intense and lacks the overarching story.
Mahoutsukai no Yome (The Ancient Magus Bride)
I think this one goes without saying. Good looking anime, with a slight shoujo appearance. Humorous but gritty all the same, it has some similarities to Shuumatsu nani Shitemasu ka? (WorldEnd) in that a character is suddenly brought into an entirely fresh world that they'd participated unknowingly their entire lives but never understood completely.
Shoujo Shuumatsu Ryokou (Girls' Last Tour)
Another 2D-3D blend, although it's a chibi-take on that theme. An incredibly cute and lighthearted take on what appears to be a post-war or post-apocalyptic world. The banter between the two characters is heartwarming and innocent. Unlike anything I've seen before.
