Nice little fellow. What is his breeding?
He will look a great deal different, when clipped. How tall is he?
He is bum-high at the moment, but that likely will straighten out as he ages.
He does toe out, on all four feet. I would like to see a higher tail-set on him also. He has a pleasant enough head. Nice enough rear and forelegs. In one pic, he looks as though he might be over at the knee, but I don't think he really is.
His neck could be slightly longer, if for the show ring. Show and breeding Minis have quite swan-like necks, these days. Again, that might change and look better, as he becomes a grown, adult. His shoulder looks a bit straight in one pic, but not bad in another. Can't see his feet. Many Minis have club feet. His eyes look weird in every picture.
Overall, if put in show condition, he might be quite nice. Have you had him colour tested?
Is he whole or a gelding? Registered? What are your plans for him?
