I strongly suggest that when you make an animation of this type, an animation without any audio to accompany such as dialogue or music, that you create a beat for the piece. Using a metronome (if you don't own one you can use this one
http://www.metronomeonline.com/) and find the beat you want for your scene. Break it down to beats per 24frames for the xsheet and mark where the beats fall.
In your case the beat might the the jump beat. Once this is established and the xsheets filled in with where the beat falls you can decide where to put what movements. Combine some movements on double and triple beats (pauses) and some on half beats for variety but always try to follow the beat. It will give a professional quality and 'feeling' to the whole animation that will immediately improve it without touching any drawings.
Remember in the xsheet the accent in the movement (you have to find where that is, from your timing charts and visually) goes a few frames before the actual beat position in the xsheet. In the Illusion Of Life this is more clearly explained.
Do this and let's see if we 'feel' a rythm in your aniamtion with the next test.
Technically the animation is good, only the looks need more time. But let's see the next version timed better before going on.
