Wow Appy you are quick! That is a Morgan trait. Not the uphill, but heavy in the front and lighter in the back. It's a not a conformational flaw in a morgan. I woundn't say that he is post legged either.
No I love my Morgans but I do see one of two "flaws" in my opinion. I'm not a huge fan of his head. Morgans usually have such elegant head, his not so much.
And he desperatly needs to see a set of nippers for those toes. Once again this is my personal opinion, I like my feet perfect!
Overall he is a realy beauty! Love his color, it looks like he has a really sweet, honest eye, and his mane and tail are wonderful .
I love forward to seeing more of him!
