Ears. Trying not to be judgmental here, but they're really weird. 

Despite their sensuous properties, they're quite unwieldy. 

When I draw them, I do my best to do as little with them as possible, so when it came to sculpting one... I was more than a bit lost.  

Do I work inward or outward? Sculpt a base and work up or out? 

I am throwing in the towel on this one, folks. The ear has taken me down. I'll probably have to spend a few days after January just working on ears until I understand them.
