She is cute. Love the headstall.
If that is a tiedown/noseband, it is on incorrectly. It should be put on before the headstall goes on. It's probably interfering with your horses bit. And it's also too low on your horse's face.
This is a proper tiedown fit. Then the headstall and bit go on afterwards.
What type of editing program do you have? I love the flower border.
