Yakitty-Yak!

 

Here's a couple of yaks I've drawn recently.  I like drawing things with lots of fur.

Here's the reference images:

There isn't really a vast supply of free stock images of yaks on the internet but it sure beats trying to find photos of wooly mammoths.  There's a fair amount of paintings and renderings and skeletons out there but they are somewhat hampered by the fact that they aren't around anymore.
