You asked for some detail so some extra comments for you.
Forequarters: Upright and shorter pasterns, shorter and strong limbs, longer humerus bone with an open shoulder joint and slightly upright blade, all of which collate with a forward set wither. - This fore is oriented to a typical western short and stronger stride.
Core: Back a touch long, but it is well supporter by a deeper girth, large river barrel - once again encouraging a strength oreinted stride
Hind: The hind is good/resonable and the strength of the topline. - Strength oriented again.
Overall: Slightly longer body and shorter neck, nice even neck set. Very consistant traits throughout towards western. Likely faster and flat low profile stride. Quicky into full stride.
