Keep practicing
I've made hundreds of this type of still frame animation. This movie is pretty good, keep practicing and you will keep getting better and better over time :)Believe me I know the work that goes into this! But I realy enjoy making these.
If I can get ahold of my cam-corder, I'll see it I can convert some of mine to flash.
Good work and yes when I made these types of animation, background sounds like little sisters or the phone ringing we're very anoying.
Question, did you add the voice and effects after recording the animation, or while you made it? I added mine while I was making it.
Cheers :)
