There are so many great elements to this image; the dried milk on the forehead, the white eyelashes, extra long ears, silky whiskers, a puff-ball forelock, all are quintessential foal delights.
To top it off ,she has a yin yang symbol on her muzzle with the play of white to black. Yin yang is opposite but interconnecting forces, philosophically speaking. There can be no light without dark, no up without down, no positive without negative, no open without closed, no life without death, etc. The symbol represents the interconnectedness of the world, particularly the natural world. I think these markings are perfect for this little soul.
