Wow, Im not trained in the ways of conformation, but I like a balance horse. And both MArio and Sophie are that. With the exception of that belly Sophie has, and yes, I really am with you there in the pregnancy suspicion... But even tho MArio's butt is a little sloped. He's STILL built nice (IMO) and just a gorgeous little fellow!
Sophie has a pretty face, and besides the belly and awkward leg angels, still very nice! She is NOT ugly! He should be able to help with the pigeon toe- like Cat said.
