Thanks guys, but I've just been dumped!
Well, not me. I'm still in the game, but the tune has been removed from the equation. She was really happy with it, but she showed it to her lecturer with an initial version of the film, and he said the music was too over-powering and drove the film, distracting from the visual content.
Now, I think normally this would be ok, but she's trying to create some visual imagary that you have to think about. Apparently my tune kinda drowns this out - makes the whole thing too industrial, where as it's supposed to make you think. Now she's got someone else to do it, cos she was afraid to tell me she wasn't gonna use my tune!
Oh well.
