What do you think of this horse??? Warmblood X Welsh Cob X Paint???

I just tried this horse out last monday. I have owned horses before but all 15hh and up. This girl is 14.1, but she is a Warmblood/welsh/paint. So she she has the huge stride of a warmblood so it feels like your riding a 16hh horse. She's only 6 though, younger then I would have liked but they told me she is used as a beginner horse in there lesson programs, so when I rode her she is soooooooooooooo calm. I plan to use her for the hunters and possibly jumpers. My coach told me that she has the potential to jump up to 3 ft. When I was riding her, she has a very smooth jump, so I no that would be true. She also has really good conformation to be a good little hunter/jumper. So yes we are buying her.
Take a look.
