Not bad... but could be improved greatly.
I am not gonna harp on the fact that this type of movie is becoming WAY to common on newgrounds. Hehe, this one even had the characters being built in the the beginning; how original. =/
Aside from that, I think that you should spend a bit more effort good voice acting, and possibly better mouth animations. These 2 things are extremely important! I would also recommend finding an ACTUAL GIRL to do Sydney's voice. I mean... seriously...
Also, I noticed that this animation was pretty much completely devoid of any sound effects except for dialogue. I mean, we can't event get the everlasting harp sound for a flash back... or something?
As I stated before, I think the real issue with this film is not necessarily the animation/art style. It is mainly in coming up with some convincing voices and effects to compliment the good writing. Good luck!
