Post pictures and it will be easier to evaluate.
As a whole, western saddle fit isn't THAT drastically different from English. There are fine points, yes, but a poorly fitting saddle should be pretty visible. You can always put the saddle on your horse, lunge her until she sweats and then examine the sweat marks - which should be even without dry spots, as a general guideline.
Is your horse bucking and carrying on in English tack or just the western saddle you suspect isn't fitting correctly?
