Hi SilverCharm,
I too think she is a nice looking filly, I have a couple of questions for you and some suggestions.
First the questons:
1. Is she registered with both the American Quarter Horse and American Paint Horse registries, or is she a breeding stock Paint?
2. While it sounds like she has some nice bloodlines and looks like a nice filly, some of the lines you mentioned are older lines do you have anything any closer? ie; Three Bars is a 1940 foal.
Now the suggestions, to me she looks like she has a nice head and neck, I like the shoulder very much and can't tell too much about the hip. But she looks pretty well balanced, and well muscled for a two yr old. If you decided to post a picture of her when you sell her you may want to brush her mane to the off side to show off her neck better, a good neck is a sign of a nice moving horse, good balance (different type of balance than mentioned before, the first type is she is put together evenly). The second is stand her up with all four feet under her better too show off her hip better, in the picture her leg is behind her so you can't tell what type of hip (engine that drives the horse) she has.
You have received some good advice from others, and I agree with most of what was said. But remember if you have, lets say a $2000 horse now and you spend $1500 to get her started and able to ride so now she is worth $3000 to $3500 don't spend the money just sell her as she is.
Your area has alot to do with how much she is worth, but if you can answer my two questions I will give you a better idea of what I think she is worth.
