Hey DK!
I've added a pair of ears to your model. I hope you don't mind.

Just duplicate the layer 2 times and add an ear on each layer. Then order them by depth along the time line properly and you can hide or show the ears above or behind the head.
To distort the ears just draw them far away and warp by a strong bone. That bone have a scale keyframe stored at frame 0 (like I do in my tutorials for the springy mechanism) that gives a frontal look to the ear at frame 1 (it was scaled from 1 to 0.25). Then restore the original length of the bone when turn and place it in the correct position.
Also have fixed some minor issues with the hierarchy. The neck behavior was not symmetrical. Aslo added a true central bone to link all the symmetrical bones (the two big that scale the face and distorts the head, the scaled bones of the face, and the bones of the ears) Now to bend the head right or left you have to manipulate the central one. I think in this way the skeleton is more consistent. Also increased the strength of the big bones of the head to properly distort the head circle.
Also is strongly recommended to store the maximum turns in actions to avoid to have to tune the left or right turn every time. As well as the turn doesn't depend now on the bend now is easier to combine actions together.
The nose is other story ...
What do you think? Please play with the file to see if it works like you want / need...

BTW: I love how the head distorts!! it is perfect!!! Those two big bones make a very good job!! scale and rotate a little and that's all!!
