Hmm, that does not look good to me at all. I'm no expert and clearly not a vet (yet) so I do not want to throw out any possible issues until others have taken a look at those pictures. I would definitely bump up his humidity to around 65-70% right now since he just went through a bad shed and his scales appear shriveled, he is probably dehydrated. Be sure his substrate is clean and dry while the humidity is satisfactory.

It is fairly late right now, so you probably won't get the best responses until tomorrow when more people sign on. Hopefully someone can give you come clarification here, I'm sorry I could not assist more!
