Looks like a paso to me also...I have one, and they look just alike. The short body frame from withers to rump, is exactly like mine. Great riding horse, so smooth, ride him on loose reins, and let him have his natural gait. It may seem fast at first, but it is so smooth.
I actually ride mine with a bosal, no bit. But when others ride him, I use a paso bit...I think it is called a spoon bit.
Im definetly no expert but before I was able to ride I would quiz myself on horse breeds by looking at a pic on the internet and seeing if I got it right...all I can say is my first impression was part QH but I don't really see that in its facial structure.
