You need more practice. It seems you understand how to animate smooth madness movement, and you are trying to. You almost succeed. But it doesn't look smooth because it's rushed. You need to use more frames in your animation when the object becomes slow, and move the object by smaller steps when it is changing its movement direction.
Madness characters walk by a sinus wave. A sinus wave is when the character moves up/down with proper acceleration/deceleration. ALSO acceleration/deceleration is very important in a frame-by-frame animation.
I'm your fan now!!
