In that first picture it looks like she's got some shed left on her. You can try soaking it or just let it come off with the next shed if any of the retained shed isn't completely circling the body. If any of the shed wraps all the way around the body... you should try to get off as much as you can. Also... 50% - 80% is quite a big range. Typically, my humidity is at 60%. If a shed is coming, I'll put a humid hide in the cage for her to get moisture from. Last time I did this she shed perfect... and she was only about 50 grams at the time.
