A lot of foals I've seen are severely downhill, but for a baby, he's surprisingly square. There's not much you can say right now since he's so young, but please keep posting as he matures! I want to see how he turns out. :)
Shoulders look good, but does anyone else think his withers seem flat, almost like his neck just sprouts from his back? Hocks could also be a bit far out from under his hip, but that could just be the way he's standing. Otherwise he's a lovely boy, difficult to tell length of neck, evenness of the top line and quality of the head on foals, but I'm sure he'll shape up. Minimal whites are my absolute favorite.
