Not really. It looks to me in the pics, that she is back at the knee (chair legged) and very straight in the rear. (post legged) Could be the way she is standing in the pic. Also, put your hand over each part of the first pic. She seems to be a lot more horse in front, than in the rear. You will be able to build up that rear somewhat, with work up hills. Could be she is just still out of condition.
Something else I noticed - and I could be all wet here. Have a look at her rear in the pics. Do you see, just under her tail base, a tiny indentation? It shows in both pics. Have the vet check her vulva. I had a mare years ago who had this same look and she needed a Caslicks procedure. On your mare, it could be just a condition problem, but just in case, have the vet check her for that.
If you don't know about that, have a look here.... Vulval Conformation, Common Vulval Injuries and the Caslick's Procedure
Please don't be offended in what I have said. Some or none of it might be true, but I'm just saying what I see from the pics.
She is a nice, stout little horse and should be a good companion for you, for years to come.
