Wow! His main is so cool! My Curly's main is hardly there, but what is there, is wavy. When dry, he has the marcel wave and when wet, he looks like your boy. My guy has a long tail that is tri colored and has slight wave. After seeing pictures of yours, I'm even more excited to see what he may look like next year.
The air here in the winter is very very dry. Every time you touch someone, you get a little zap. After brushing your hair, it stands straight up with static electricity! I have two curly haired daughters that have the frizzy fly away look going on. I think if my Curly horse were around a little more humidity he would definitely curl more.
You are right. This is an awesome breed. He's a fantastic horse for a beginner like me!
