A quick sketch of Asami Sato going donkey. Head only as a practice to do frontal on model tf.

I think it's not too bad (compared to most of my attempts.) I need to remember to practice using layers more. That and maybe try a different freeware drawing program.

Either way the real limiting factor is the mouth and nose area. I'm not sure how to properly do lips when the expression is "shock and horror" and not arousal.

Anyway, you can see that the right ear is playing tf catch up with the left and that Asami is well on her way to some state of donkey-dom.
