I think it's tied on the wrong way. I can't see it well in the photo but the tail of the rope goes through the eye on the halter then it goes around the eye in a half-hitch. If the knot is tied above the eye then it will slip and the halter will loosen and come off. If that is the way you have it then great it looks fine.
There's nothing like the Rockies in the springtime... Nothing like the freedom in the air... And there ain't nothing better than draggin calves to the fire and there's nothing like the smell of burning hair. -Brenn Hill
