These photos do not help a stallion prospect at all. All I can judge at 6 months old going thru the just weaned 'uglies' is his legs. He looks a bit back at the knee and camped under (sickle hocked) behind. He also looks like he might be knock knee'd in front and truly cow hocked behind. HOWEVER, these photos really do not do this horse service!! He may be a LOT better than these images indicate!!
That being said, get better photos. Even wooly he can be groomed, stood on an even surface (like a driveway) and set up with the legs toward the camera square underneath him and the front leg away from the camera back a little (space to the knees) and the hind leg away from the camera forward a little (space to the hocks) and the person operating the camera standing opposite the horse's hip bone. You need three people. One to operate the camera. One to set the horse up and hold the horse and a third person to get the horse's attention (ears up and head up). RANT
(in general, not directed only at the op)
I have never understood why so many posters put up unflattering photos of their horse for critique (this, BTW includes these photos but as a general comment).
Here is their horse.. and often their pride and joy and something they really like and they take and post a photo that detracts.
I would be mad as heck if someone posted a photo of me when I first got outta bed in the morning making Phylis Diller look like a Beauty Queen! It is a good thing horses cannot use the computer.. HaHa.. If they saw some of these photos they might become totally intractable! END RANT
