Hmmmmmm....
You kinda act like Tweening is a bad thing or something....tweening coulda made it easier on you...not to say not tweening is a bad thing either. This is stellar work and I like it a lot, but to be a bit anal. Although "tweening" in Flash terms means using either the shape or motion tween option, tweening is short for inbetweening which is common place in hand drawn animation as well as 3D animation....tweening is just all the frames "between" the main frames used to transition the animation from one move to another.....so to be technical.....you did tween =P
Good job...even though some shape tweens or motion tweens would of gotten the same results. To all other authors....tweening isn't a crutch...it's a time saver!
