What is your opinion on her scales?

[Kagonos]

I have an approx 3 year old female bcc. Her scales have started to... fold, crease? Where she normally curls up. I haven't gotten any good info on why this is by searching the internet. They are not burns, that much I can promise, it isn't possible in her enclosure. I'm wondering if perhaps she is overweight? She eats a large sized rat every 21 days or so. I'll add pictures to show what I'm talking about. Thanks for any help everybody. Any ideas would be welcome.
EDIT: I'm on my phone and I can't get a picture to fit, I'll try and embed a link.

I don't see anything unusual, and just so you know, that is a hypo BCI and not a BCC. :)

I get lines like that when my humidity is a tad too low. Most of the time, they'll still shed whole pieces, but I like to try to keep my snakes as hydrated as possible. It drastically increases their colors, and they just look overall healthier.

Indeed you are correct. Salmon Hypo BCI. Dunno how I got the BCC in there.

Thank you, I was concerned that maybe the humidity was low but she always has such good sheds I didn't want to mess that up.
