You'll feel much more at home here in the Students area.
I really have no suggestions on this. You've done a pretty nice walk cycle.
Could it be improved? Sure, but improvement takes it out of the basic exercise and takes it into storytelling.
If you want to pursue that by all means do!
It is said (Walt Stanchfield I believe) that when you animate you must animate verbs not nouns.
This is to say think of the emotion that drives the motion.
Think of the mood that drives the pose.
Is s/he sad? (Looks a bit that way in your walk cycle) Play that up perhaps with drooping head if appropriate.
Where is s/he going?
What caused the current action? Why walk across the floor at all?
Now that you ARE the flour sack ask yourself these questions and formulate more of your own.
