From the first picture I think he look's pretty good, except he looks very straight on those rear legs, an wonder how he travels. Second picture don't show much .
He looks to me like a solid calf, however i would like to see him a little cleaner up front with a little more extension. I dont know if it is just because of the way he is standin in the pic but he looks like he may not have much base width from behind.
I'm with Freddy on this one. Hate to say it but he looks a little Aliasy, if you will, being pretty straight on both ends. Hard to really analyze structure in pictures though
