He is adorable!!! From these pictures, it looks like he is a bit ewe necked and he seems to have long pasterns (Hard to tell from the pics though). But, he looks like he has a really nice back, good high withers, and straight legs. He is preportioned really nicely :)
He's pretty decently put together...nothing extremely glaring pops out at me, atleast. A little long in the topline, and appears a bit downhill built. Can't really tell about the pasterns, because of all the fur on his fetlocks...he does appear a bit 'low set' on them.
