Hey Ady,
No, I'm not asking for stills, but I think that you should let someone watch the movie before you release it. I think that a 'beta-release' of the movie to some people will be a smart choice because even you can make mistakes. These people can check the movie for mistakes, and then you can correct those and release the final movie in the end.
Just an idea, but think about it. Some of the screens you already showed us, had some mistakes and the people on this forum discovered them and you corrected those. So maybe a beta-release to some people?
