If you're looking to sell her for $1,000.00, you're going to need some better pictures.
Although many of us can look past hair, she should be well groomed and stood up properly for pictures. The ones you've posted make her look like a goat.
Conformation pictures are advisable. People who are knowledgeable want to see the horse from both sides, and front and back if possible. Include all
of the horse in the picture; don't cut off her feet, head, or tail in any of the shots.
The pictures should be recent; no older than several weeks. Posting pictures 3 to 4 months old is unacceptable.
