those ropes are tied around her hair, they should be so loose she could slip out
her shirt is clipping through her skirt and her skirt and hands are clipping through the couch.

what you should do is use the camera tool to line up your shot, take one photo of the whole image, then use the material tool to make the couch invisible, take a second shot. use submaterial tool to make the skirt invisible and the ropes too and the then take a third shot.
organize the layers and erase the parts that looks out of place so it looks like the appropriate thing sits on top. you could also erase some of the back of the upper ropes so it looks like it under her hair
