Mmm, I guess I have a thing for works that appear light and warm on the outside but are pretty dark and psychological on the inside, when I came with the idea for my story I was reading Asano Inio's Oyasumi Punpun, I really liked it, and as I went on I came back to my core fundations, my main inspirations:
-Neon Genesis Evangelion (Hideaki Anno)
-Revolutionary Girl Utena (Kunihiko Ikuhara)
-Puella Magi Madoka Magica (Urobutcher/Akiyuki Shinbo)
All of them have this thing, they look nice a lovely on the 1st stage them turn freaking psychological and dark. A recent example of this could be what J.C Staff is doing with DanMachi, there are some parts that I say, daaaarn this has some darky/psychological undertones.
Then I just threw in a bunch of things I like in general: naked peeps, horror, surreal, absurdism... and the avant garde direction of Akiyuki Shinbo (mostly on Monogatari). And I fear I might get excited and make this ultra long, so I'll stop here.... 8_8
