hello new guy with adopted snake

I'd say the culprit to the shedding problem is low humidity, as I can see you're using a heat lamp on a cage with a screen top. Warm, moist air rises, and cool, dry air enters the cage as a result. The lamp dries the cage out. Are those aspen shavings? (Pine releases high levels of toxic phenols). Low humidity causes low-level chronic dehydration. Without enough fluid in the body, the snake cannot produce the lubricating fluid that separates the old skin from the new, hence the old skin sticks, and won't come off. (It's also hard on internal organs).

So, my recommendation would be to pick up a heat pad that will cover about half of the cage bottom, and a good thermostat to control it. Lose the heat lamp, and cover all but 1 inch of the top with plastic wrap, and place the water bowl over the heat. If the humidity is still too low, consider switching to Cypress mulch, and misting occasionally. Humidity should drift between 50% and 70%, with an average of 60%. When the snake goes into shed, raising it to 80% will be beneficial. Be sure the bedding is never wet.

I also see a stick-on thermometer in the tank. Those are inaccurate by as much as 30F depending on room temperatures, making them useless. You can pick up an indoor/outdoor thermometer with a remote probe for around $12 at Walmart. Place the probe over the heat source on the cage floor, where the snake will be. The danger at present is that your snake can get up quite close to the heat lamp, and you can't really be sure what the temperature is at the point on top of that log. Burns could occur.
