He looks shiny as in freshly shed? Is it possible for you to have missed it or have you searched his enclosure?
Some people say they have had snakes eat sheds. :shrugs:
If you don't see any signs of dry skin or bits of skin hanging off of him then you are probably in the clear. He might be taking longer to shed this time. I, personally, haven't had a snake go that long after clearing without shedding, but my experience isn't as long as others.
