I'm going to have to say, please don't breed from her. It may just be the bad photos, but though she may have a great temperament and you love her to bits, she is just not a broodmare candidate.
You are much better off buying a weanling or yearling. Go to a reputable breeder, where the horse has papers, you know the history of dam and sire, etc. That is what I did with my youngster, I was offered a number of very good mares to breed with that would have complimented the stallions I liked, however I decided that the risks far outweighed the benefits, so have recently purchased a just turned yearling hanoverian colt.
It was great to be able to go and spend time with his half siblings, and pick from a bunch of them. I was able to select the youngster that I believed would most suit me, through temperament, trainability and paces. Far less of a gamble than breeding, and cheaper too!
