Vanilla walk Planning

My Thumbnail Sketches Vanilla Walk 

-Walk is Lean Forward with our Upper body & throw out a leg just in time to catch ourselves.These are the things that have to keep in mine when animating walks,
-All walks are different. 
-While walking body is moving forward evenly, there is no ease in, ease out.
-Mostly Up & Down poses give the weight shift in a walk.
-Arms & Torso Oppose the legs & hips

All walks are start by deciding on a tempo, then the Contact positions, where the Foot touching the ground their is no weight on it yet.
Setting the Tempo,
4 frames = Cartoon run
6 frames - Fast run
8 frames = Normal run
12 frames = Normal walk
16 frames = Leisure walk
20 frames = Tired walk   

Best way to boost up vanilla walks & stylized walks is reading the best book about walks Animator's Survival Tool Kit.
