He is of a good weight, not too fat or thin and looks healthy. He seems to have nice bone and his front legs look good and straight.
He's long through the loin, but he has a nice hip angle, long croup and proper tailset. I'd like to see more muscle on his gaskin. He's a bit higher in the hocks than I'd like - by the way this breed does NOT have hock problems.
Like you, I don't care for his neck. Too short for me.
One thing I want to make clear - Peruvian Horses DON'T PADDLE. Paddling and winging are different things and are caused by conformational faults.
These definitions are taken from a great book on horse conformation called Equine Photos & Drawings for Conformation & Anatomy:
If the horse is toed-in , the foot deviates outward as it advances. This motion called "paddling", strains the sides of the joints, although the horse usually does not interfere.
If the horse is toed-out the foot deviates inward as it advances. This "Winging-in" motions leaves the inside of the opposite foreleg vulnerable to interference.
What Peruvians have is called Termino. It is not due to a conformational fault in the lower legs. The motion originates in the shoulder.
