Yeah, seems like stuck shed.

You can try this: Take small plastic container (with air holes), fill it with water so that the depth of the water is about half of the snake's body height (inch or two). Place a damp towel in the container too and then the snake. Soak the snake in the container for few hours. Make sure that the container stays warm enough. After the soak, if all the old skin has not come off, you can use the damp towel to gently remove it.

Works like a miracle, every time
