This mare is 10 years old, a Thoroughbred and around 15.2hh. I did e-mail for more information and pictures (although there were quite a few pictures available on the ad) She's in Halifax, so it's a teensy bit better. *fingers crossed*
And here's a picture of her jumping (possible critique on form maybe?)
I don't think her conformation is too bad, but I'm not an expert. She looks to be in need of overall muscling, but that can be managed. Then she looks to have some more upright pasterns and maybe slightly buck-kneed.
