New to BP, wrinkly neck?

[RifftheBP]

Hello, I am a new BP owner (I took in my friends sons BP cause he wasn't "into" it anymore". S/he is 18 give or take inches long and first shed since we had him.
Riff (the name of the BP, thanks to my daughters obsession with barney the dinosaur) eyes have been cloudy for a few days now, not quite blue as the picks in the shedding forum. We just fed him a mouse yesterday and took to it quite well, I have read that some BP's dont generaly eat during the shedding period is this for most BP's or just some?
His neck is quite wrinkly more than the picture in the shedding forum again, looks like an old ladys throat (no offense!).. His humidity is at 45%, and the temperature is at about 80-90 during the day on his hot part. He often runs his body through his big water dish he doesnt submerge himself though.

I am particularly worried about the neck wrinkle.. I am hoping this is normal cause he really is a beautiful BP when hes not in this shedding process. I just want to take extra good care of him cause I promised our friends son that I would take as good care as he did.

Thank you for helping me, a newbie out. I have gone through forums to find some answers but any help from anyone is well appreciated.
