klangley & bardhol mentioned extension lines in the comment section. Here, I have illustrated how I have been using extension lines in trying to tackle various characters. They're bothersome and they don't guarantee 100% pleasing results, but it helps me on an initial attempt. In short, it's not a tool to use for every drawing! Take a look.
As you can see I'm still working on the basics and trying to get comfortable with the concept of "bunny ears!"
Thanks or the comments & hints, BTW! Keep scribblin'...
