I don't have any conformation pictures of her yet but as soon as I do--hopefully soon :)--I will post them in the Critique forum. Funny that you mention she could be double reg. As a QH because when I saw the ad for her my mind saw the A and the HA and automatically put a Q in the middle of it so I went about three days thinking she was a quarter horse. Which really isn't all that hard to believe seeing as she looks just like a bay QH with four white socks and a blaze but I still felt pretty stupid :P.
There are these head shots which I think make her look particularly Arab in the first one and QH in the second.
