Kinda slipping
I took the liberty of watching the teaser for Project: Rebirth, amongst your other movies. I was curious to see how your animations have grown. Unfortunately I have to say that the animation in your test movie was better, more involved. You might take some time to do some more involved animating with these. If cheap anime has taught us anything, it's that unmoving pictures in an animation can just be unnerving, and very bothersome.
Some of the prior comments stated that you should try drawing the backgrounds yourself. While the style you are using, which is to vectorize the images in flash, could be effectively used in a film noir style, I don't believe you have advanced enough to attempt such a feat. If you aren't very good at drawing in perspective, which was an issue for me for a long time, you might try tracing over the backgrounds that you want to use. Who knows, it might just offer you a bit more flexibility than you expected.
In regards to the voice acting, after watching more of your videos I realize that you are doing most of your reading yourself. That's not a bad idea, especially when you don't have actors to do it for you, however I would suggest writing out your script first before you get started. It sounds like you are making it up, on the spot, and just recording in one take.
The story seems to have some depth, and it looks like you know where you want to take it, but you aren't really pushing yourself to improve. The art looks exactly like the first video you posted, and I assume in less than a month you'll be posting your next one. I simply implore you to attempt a higher standard in quality, in both animation and script, so your story can be rewarded the respect it deserves.
