"Fill in the Gaps"-Lindsay

What a great exercise. It made me realize how little I know of horse anatomy. I mean seriously, what are those critters supposed to be? Even after I studied the reference photo (second image), my memory took over in the third and confused the actual construcion of the face again. I found that I tend to shorten proportions, and make fatter what should be thin, and what's thin, fatter. I'll be trying this with other images as well...
