the large wolf here will actually turn its head and follow you regardless of the angle you are at. the eyes also change colors. you can see the pearling that appears to be his breath. just behind and to the left of him you can see the moon over the mountains with the shadow of a wolf howling on a rock. this was a tattoo that Preston had, but his was in color. the shadowed out wolf represents Preston being gone from this life. you can see a few of the hidden animals i was talking about in this picture
