Definition: That quality or property of anything which touches the feelings or excites emotions and passions.
Ahhhhh, to be moved ( feel ). The goal I always strive for is to strike emotion to the audience and myself with the character I'm animating in the shot, to empathize with the situation. If you can pull this off, It is very rewarding.
This can be achieved with practice, translating simple ones in front of mirror act out sad, mad, happy, etc. Make note, sketch thumbnails, copy poses to 3d and see, push the pose and check if you feel affected by it.
Posture, attitudes, acting it out and coming up with subtle to broad ideas, be on the look out in public on tv for examples too .. Just have a go at it and have fun..
A great example of this in action check out a cool Demoreel, I stumbled upon from " Jennifer Hager" . Some wonderful heartfelt Pencil test form pieces that are in sequences connecting. Indeed very inspiring to strive for, this quality and momentum she has. See for yourself..
Bear in mind, these are only "Line drawings" so why and how does this make you feel this way?
When you forget about the animation itself and believe , that is truly gold..
