Nope, don't bother me at all. Looks like a happy young lady with an elk of her own -- I say, right on!
Just curious -- why do you find holding up the antlers while sitting astride any more offensive than holding the antlers up in some other position? I mean -- I'm a hunter, and trophy pics certainly don't offend me at all -- but it would seem to me, that if someone was to take offense to a trophy pic; the offense would be in the wild celebration of the success in ruthlessly hunting, brutally killing, and subsequently cutting up and butchering of one of the most beautiful creatures to walk the face of this planet. Assuming that sort of thing bothered you -- the particular pose chosen for the celebratory photo would seem to be rather unimportant. And by the same token, if all that doesn't bother you; why does the pose?
Serious question.
