My older girl gets a little wrinkly like that and has an almost greyish tint to her just before shedding as well and sheds all in one peice.

At this point I would just make sure that her humidity is bumped up, don't soak her just yet. I would wait until she gets most of it off herself and if there are still bits of stuck shed on her, that's when I would soak her.

From the pics I would get 2 identical hides for her tank and maybe cover up 3 sides of the tank so she feels a little more secure. There seems to be a lot of open space.

Very cute little girl!!!
