"...is a collection of imagery, film and music to build an intense atmosphere..."
That's sure worked for me, I found it really immersive with many deep different feelings. I found it fantastic but like all the art work this depend a lot on the person is watching, for some other this cold mean nothing.
Why don't you show your work in some short film competition or festival I'm sure you've some good chance, I'm not speaking about the technical part but for wich concern the artistic part, that in my opinion is very good, i'm say good not like thing you can find usually on the net but like a professional work.
Just some advice that I think could improve the movie...
1- Put a "Play" and a "Pause" button.
2- Increase the volume of the music, it's my pc or is very very low.
3- Use some more soft-edge fonts for the writing or better different ones that match with a particular part of the movie, this would improve a lot the feeling expressing of the writings.
4- Some time the animation on the background have too much bright and contrast, I know that that is the effect that you would obtain but sometime it's hard to see even something.
