All my animation sketches go here:

Sketch Test 1

You've got the forms right but your movements definitely need more work.

Adding more frames for "A little something" and "Sketch Test 1" would do wonders. "Sketch 2" lacks 'umph' and the "charging" motion needs to have more frames. Sketch 3 is decent but it's too short for me to actually like it.
