an improvement, but...
Now there's even less animation then before. A tip: do frame by frame. And remember: movement is fluid, and people have joints. Meaning, if you are moving, chances are, you move more then one body part.
example: when you reach for a can, you bend your arm up, extend your fore arm out, open you hand, and grab it. FBF allows you to make your animation look more fluid and realistic. Tween is better for backgrounds, and small movements, like moving your eye, or zooming in or out of a scene.
For example: tweening just one part of an arm makes it look clunky, and robot. FbF, even tho the arm is the only part moving, since it is impossible to perfectly redraw each frame, the characters whole body appears to slightly move a few centimeters. This flawed motion actually looks more natural and even tho it's harder work, it will make your animations look ALOT more professional.
Plus, if you ever get a tablet, it'll be even easier to do FbF. Anyway, not bad, but next time, more animation, and check out my review of your first gaia blade anim for more tips. Not bad.
