Ive seen horses with worse..but it doesnt look like something too horrible.
All I've found with steep shoulders is a shorter stride that's less comfortable than a horse with a more sloped shoulder.
Im not sure what discipline you ride/show in, but dressage might not be the best one since her extended strides won't be as extended as prefered, from what I can gather through my experience. Never again will I buy or lease a barrel horse with a steep shoulder, because I had to improve my seat (it did teach me something and to become a better rider) just to stay on going staight on her, much less not be holding the horn for dear life in our turns, lol.

Arabs are commonly base narrow in the hind end? Hmmm, never heard of that, mine weren't. Anyhoo, a picture without the saddle squared up would be better to judge. Looks a tad sickle hocked but pictures can make or break a horse, so to speak.
