Please Critique Dusty :)

This is Dusty. He's a 12 year old solid paint horse. He's grullo in color. Please critique his conformation. I do not have a picture of his hindquarters yet, but I'll have one later today. Edit: I have no idea why the attached picture is upside down, but I also don't know how to fix it on an iMac :/

Oh what a feeling! Your horse is dancing on the ceiling!

Haha I know right?! It shows up the right way on the computer, but it refuses to go on the post right side up!
