Animation Notes_Skateboarding From Wreck-it Ralph

And Here's my practice:
try copying this shot and learn the body mechanics

First observe the motion trail that she travels from start to the end,and clearly it's an S shaped curve.

When posing,I have to decide the weight shift.I try to balance her body and think about the weight shift from one leg to another.

Aniticipation:
One of the most important key pose is when she twist her chest for the plunge.

Everytime she is about to slide,she will bend down her body,moving the center of mass to the other  leg.Notice that the spacing is uneven.It will give it a sense to rush.Move fast at the beginning and settle down at last (Slow in)

When she is at the highest point,she stands nearly upright for cushion,preparing to go down again

Her waist and chest arrive one by one (Overlapping)

However,when she turns or speeds up,she will shift weight to the front,so there will be an angle between her and the skateboard

 

Though the picture is dark as she skates through the tunnel,we can still assume her motion trail.

When she is up at the highest point the second time,she is preparing to go down again,shifting weight to the front leg,and lowering her body.Therefore,the board will tilt down and move downward.
