Blimey!
This was a really, really, long flash - you must have worked a long time on it, well done. There were some nice artistic touches to this, such as the cut from one person to another as/via the nails and the dove in the man's glasses. The animation was alright...but then this was really long (my screensaver came on twice lol) so it would have been hard to make it meticulous.
The music was well added as well, although the sound effects were rather clumsily done. Coming back to the music, some of it may be unsuited to the flash just because of its associations - i.e. the X-Files tune (although this may only be me) seemed a bit out of place here - only because it made me think of the X-Files.
The only issues I have with this is the lack of speech and the lack of subtitles. This would have been so much better had there been voice actors and although I know German, as does the previous reviewer, many will probably not, so subtitles would really have helped with the score. If you need translations in your future works, then i will gladly do it/them.
Other than that, gut gemacht
