But he becomes so impatient he falls asleep and then wakes up suddenly.

So he is knocking on the door as he is in a rush, with the foot taping to show the character being impatient. The final animation is a character, knocking on a door with his back turned as he is swinging his suitcase waiting for another character to come out the door. For example, when rigging a simple character's arm, you can make the forearm layer a child of the arm layer, and the hand layer a child of the forearm layer. However the video below is the final animation, from the node view in the image above. Harmony lets you build your rig in an elaborate hierarchy, allowing you to set which parts of your rig should influence other limbs, and how they can move independently. The image above shows the node view, for the final animation where I have moved all the layers and parented them to the appropriate videos together allowing me to make sure all the movement flows nicely. The image below is a final node view for the final animation, where I have combined all the suitable layers and deformation layers, allowing me to move all the components of the character movements to move naturally.

Furthermore I have parented the deformation layer of the arm and the peg for the hand, allowing the arm joints and hand to bend/ move together. Next I needed to sort the layers in the Node view, here I parented the joints and layers together, in the image below I have moved the layers into a suitable position to parent the layers together easily.
