What kind of substrate to you have? And what is your humidity? I like coconut husk substrate because it holds a lot of water and doesn't mold. I'm guessing the stuck shed is from the heating lamp, that will dry things out in a hurry. Personally I'd bump up your room temp to 80F and switch to an under tank heater thermostat controlled set to 88F and ditch the lamp.
My SD retic was like that when I got him, he was on aspen with a heat bulb. Takes awhile to get rid of a stuck shed like that, you'll probably have to soak multiple times, I'd probably feed, wait a couple days, then soak at least once a week. I have another ball python that suddenly had a stuck shed and it took a long time to unstick that one LOL. Not sure what caused that one, he was on damp coconut husk substrate the whole time. If your snake has the wobbles, usually from genetics (certain morphs) you'll have to make sure to watch or assist during soaking so they don't drown.
