A very cute girl and a nice project for you. That said, she does look like two different horses. Place your hand over each half in the pics and you'll see why. She is a lot more horse up-front, than in the rear. She seems to toe out slightly, on all four feet. Moreso in the rear. She does seem to be pretty up-headed, which isn't necessarily a bad thing. She may be slightly down hill, but not enough to really consider. Looks to have clean legs. Certainly sports that usual scrawny tail of Appaloosas. She looks to be in fairly good condition and maybe a bit younger than 8?
Good luck with her and keep us posted. She's really pretty.
