I know you took him to be evaluated, what did the handler you worked with say about his show potential? She did a good job stacking him and his rear looks a lot better in these pictures.
My biggest concern would be his front assembly. It looks like it is too far forward on his body, which does several things. It makes his neck look short, and his body look too long. He may when he fills out start to elbow out a bit because of the short upper arm bone.
He has some nice qualities. He has great bone and substance, a nice rear, good feet, balanced head in profile, although a bit more stop. His brisket is to his elbow, and he is a very dark brown. His eyes may darken with time too.
I hope that he turns out. He has a lot of growing to do and they sometimes grow in stages.
There were times I would worry about Reggie. For one he went through a stage that he could not handle his rear angles. He could hardly run without falling over himself. Then, for a while his croup was so steep I thought "Gah, his tailset is too low and croup too rounded" That fixed itself. For a time his topline was bouncy, he has mostly recovered from that too (was recent). I was obsessing over every little thing, and he seems to have come together. Can't get rid of his Steven Tyler lips though.
He's slobbery.
