His shoulder is steep, his neck is set a bit low and he is a bit pigeon breasted. He is very down hill in build. He has adequate bone and he is a bit straight through the hocks.
What is really concerning is the obvious rotations and offsets in the front legs, most notably the left front. That leg has the forearm looking straight, the knee and cannon rotated to the outside and the fetlock joint and pastern rotated inward. There is an agle inward at the knee making this horse a bit knock knee'd. There may be an injury to that knee as well.
Go and look but be sure to get a full PPE and be sure to look very very hard at that left front leg.
There is something about the outside of a horse that is good for the inside of a man. ~Winston Churchill
