You can upload the pix to a site like photobucket.com and re-size them. It is really hard to take her in as a whole having to scroll back and forth so you would get a better critique with smaller pix.
What I see is that her shoulder is very steep and her croup is very short and steep with a high tail set. She looks a little bit cow-hocked and her neck could be a little short (again hard to tell from these pix). Her head is pretty and really doesn't look that much too big for her body.............I don't think...... LOL.
Her face profile is nice and straight with a good nose, her jaw could be a bit cleaner but not bad. Her eyes seem a bit small but she could just be falling asleep.
Oh, and just for future referance, hands are in 4 inch incriments. So a horse's height would be judged 14h, 14.1, 14.2, 14.3, 15, 15.1, 15.2, 15.3, 16, etc. :)
