Where ya been G?! We missed ya, there's not many decent animators anymore (meaning people who can actually animate smoothly) Anyway, 1. good luck with flash, you can get a serious career in it
2. I <3'd the kick, but I hated the wave 0.0
If i were you, honestly, I'd practice with pivot kind of, cause I heard flash is easier, and being able to animate, well I guess under more difficult circumstances would sound right, you'll probably improve quicker.
