This was short, slow and had almost no build up to your main point.
I don't understand how being kidnapped by a spaceship leads to going beyond your boundaries, or how any of this is related to a 'Mechanical Angel'. What represents the angel? What does the pipe (which the little dude thing is shot out from) represent? Why was the little dude kidnapped by a space ship? Why did he (or she??) need to break out of where he was? Was where he was a larger spaceship, or a planet, or what? So many questions, not NEARLY enough answers. previous comments have said this was simple, but I thin what you have here is the beginnings of a much more intricate and complicated story.
'Who was the little guy? Is he human, or another race?'
Devlin7 asked where the story is. What you have here is a message unconnected to most of the animation. 'Sometimes we all need a little help escaping our boundaries'- you had 1 minute of film, and 5 seconds of an actual event, when the little dude's kidnapping ship broke out of some wall. that's it. Devlin7 is in no way a retard for asking where the story is.
All in all, the flash seems all point and no pike, like a pie without filling, pen without ink, if you understand what i am saying. I understand that your 1 minute constraint left no room for extra stuff, but the part where the little dude is shot out of a pipe? You could have cut that and filled it with something else, another event, maybe at the end like he lands on earth and sees some one else.
Your flash skills are pretty good. the quality of the image was nice, the pictures were smooth and you used some good techniques for the special effects, the like overlaying the pictures of the space ship moving around the boundaries of the original image a little to create the effect of moving and vibration. The music was also good.
I think you have a lot of potential, so try redrafting this story and making it longer if you have the time, because I am really interested in what happens before / next, and disappointed because I have nothing to keep me on the edge of my seat. Maybe write a back story?
Music 7/10 (although it fit the animation, it seemed too pop and light for the fact that the guy was kidnapped :S)
I don't think this animation deserves front page, because surely there must be some better stuff out there, your other work being among 'that better stuff'. This may do it for some people, but for me, not so much =/
Well, good luck anyway! :D
