well, a lil blurry is a understatement by far.
anyways, first thing i would do its wash the snake if it hasn't eaten recently. make sure its not filth.
second would be to remove the aspen and put paper towel as the substrate until it sheds. just to be safe then sorry. and if its gone with a shed then your laughing. if not then it may be time to get looking into it. most scale defects should be gone with a good shed so if there not it usually means something is up.
