Good motion begins between frames.
The drawing shows the shape. The spacing reveals the intention.
#Look at the distance
Draw a small sphere in three positions. Equal spacing and equal frame durations tend to create constant motion. Place the first positions closer together and the following ones farther apart: the sphere starts slowly and gains speed. The difference lies in spacing, even when the drawing barely changes.
#Give the gesture time
A short pause before a jump prepares the eye. Holding the landing pose gives weight to the result. Before adding drawings, experiment with how long each pose stays visible. In Zyggs, one layer’s duration can change without stretching every other layer.
#Compare with the previous frame
Turn on onion skin to follow the trajectory. Track a recognizable point, such as the center of the sphere or the tip of a flame. Does it follow a coherent path? Is a sudden change intentional? Watch again with the references hidden and judge the complete movement.
#Exercise
Make two versions of the same jump using the same drawings. Change only the spacing and pauses. Notice which feels light and which feels heavy.
