Hi,
Did you check the shed she had a few days ago to make sure she shed the skin in her nostrils?
I try not to get too worried if snakes wheeze during handling as they are generally excited and breathing heavily at that point - I would monitor her to see if she wheezes while not being handled, leaves mucus on cage furniture ( including the waterbowl ) or sits for long periods with her head raised and her mouth open.
I don't see anything in those pictures that would make me concerned. But monitoring is never a bad idea.
