He is very cute. No white, I love that! It's funny, I love the loudest colored pintos and then the solid no white horses... =P
Besides his thin neck, which you say is gone, he seems like he is a good looking horse. At first I wished that he had a large hind end, but then decided that it fits him and his body seems to be pretty balanced.
I say go for it! You will never know until you try! I think he will look absolutely gorgeous all clipped and pretty... Take pictures and let us know how it goes! =]
