Can't really tell much from how she is positioned in the pictures other than she is, in fact, a horse. To this day it confuses me as to why people post such ratty pictures for their horse's sale photos. I know the weather's turned cold and the winter coats are grown, but theres no reason why she couldn't be turned to boast her profile to the camera. At any rate, as long as you're ok with the work it'll take to train her (and if you're ok with her just looking like your old mare and not actually being your old mare), then I don't see why you shouldn't sport a gander. You might find a jewel under the bad photos.
