The picture is too blurry so I cannot tell what you are talking about.
Though, I could take a guess. My female has had two sheds where there are some patches of rough or sticky-ish scales. This comes from the snake shedding without the proper humidity level. So, when your snake sheds, The humidity level needs to be between 60%-70%, or the results could end up with your snake with patches of that rough or sticky-ish scales.
