good character style, needs work
You have the general shape down when drawing. just play with the opacity a little more there are way too many thick strong lines. Also, one thing you learn in flash (hopefully quickly) is never ever use a shape tween. unless its a simple solid colored square moving into a simple solid colored circle shape tweens will look godawful. After you've dealt with the bold lines try to make the effects more than just lines, add more of a shape to it, have all the features in the effect look like they are meant to be together, not scribbled in. Work on using more frame by frame animation combined with your tweens and it will also look a lot nicer.
