prety good
this is the first time i've seen one of your works, and it's alot better than most people, you deferentially have a style and a system that is working for you. the size and length of your projects shows your dedication, although the detail of the art works could use improvement, the style and animation makes it worth watching. In the coming years i hope to see great things in your videos.
so far your strengths are in your story telling and speed; your style makes for the speed displaying that you know what your doing, which is very important since many people jump in without a style that they do well and works for them.
something that can be improved on is the art work, but don't put too much time into it, you'll learn how you can get a lot out of so very little. your animation is fine as it is, but as you experiment with tweens start with the simple idea of using tweens not to more objects from point A to B but to reuse things, latter when your tired from drawing, mastering shape tween will feel like flash animates itself. and just one more thing that is very important in flash animation graphic symbols are your friend.
the quality of the audio was poor due to the poor quality of the recordings, something to remember even with a professional mic is to talk at the mic not into it, take a step back and speak louder, setting the mic sensitivity higher will only add more noise.
you still have a lot to learn and flash is something you can spend your hole life mastering, but keep it quick and simple you have a good thing going here.
