I know the feeling when you work on a kickstarter-project with high hopes and then you didn't reach the goal... >sigh<. However, I like this trailer!

The 3D model you use look good to me, nice idea to add some state-of-the-art Anime/Manga effects to the characters. Storyline seems to be interesting, of course this is rather hard to judge after watching an 1 1/2 minute trailer ;)
Sorry to say that, but the sound quality needs some work, sometimes the music is too loud to hear the voice actors, had to watch it twice to get all of the dialogue.

If you don't get enough crowdfunding for a 3D movie, have you considered to turn your project in some kind of an FTP game? Maybe an RPG or MMO? If you have the capabilities and know-how, you should think about this option imo.
