My family, for the last 4 generations at least, has been involved in raising dogs for conformation (among other things) so it's kind of bred into me to look at a dog (and many other animals) with that in mind. The quality of your dogs' grandma was apparent in the photo, and GSP are a very striking breed to begin with.
Only problem with getting the "oner" is that it's a bit unfair to all the dogs who follow that one, they just never measure up.
