good start
Not bad at all, very creative. I like how you are making a serious film rather than a parody or comedy like most do. I like how you actually took the initiative to do this yourself. You are very capable, so good job.
Some tips - your art is very nice, very well done, but work on your animation which is very choppy and tween-based. Use more frame by frame and maybe a higher frame rate and more fluid drawings so it looks more life like and less stiff. While the art was good, I only enjoyed it when it was still, the stiff and robotic movement is very unappealing.
Great syncing of audio, I hope you are going to use voice acting - and read up on exporting sound so your voice acting has great quality. If you're planning on getting actors, look to www.voiceactingclub.com there are many talented people there willing to help. Good luck!
