Gizmom, that's what i'm seeing.. a pinched waist.. I don't look for heavy bones.. humans don't eat that, but it should be proportional, and a 7 year old bull ought to be more filled.. certainly isn't going to get better with age like when you look at a yearling and hum and haw.
I do strive for a flat belly that isn't pinched at either end.
I think this bull could have used a better photographer.. a picture taken from lower to the ground, and more toward his front quarters would go a long way in hiding that, as well as having him in some straw.. it doesn't change the bull of course, but certainly could affect how people look at the same animal
