This is a work in progess. As you see here I have most of the shapes plotted out and I'm begining to work on the details.
Wilbur foundered when he was younger and now to prevent him from doing it again he wears a grazing muzzle when he is outside. The muzzle allows him to be outside for most of the day, enjoying the sunshine, while making sure he does not overindulge himself. He comes in the early afternoon to get his lunch of hay and gets turned back out again after he is done.
