Rain (Long version) by Motohiro Hata
I know someone uploaded the short version already but this is the one used in the movie trailer, with the instrumental part at the beginning, I love it.
Kotonoha no Niwa
Makoto Shinkai’s most recent finished production and I have to say that it wasn’t his best, but I enjoyed every minute of it. The script is as beautiful as the artwork. This is one that everybody would appreciate.
