Question about tortoise shell

[Calibri]

Hello, I have a Russian that I got from petsmart a few months back and when I got her her shell had a few bumps on it but recently I've seen pictures of shells that are smoother than this and got me concerned. I live in Louisiana and I was told it was due to the sudden change in humidity. A coworker of mine said that she was most likely wild caught. If this is the case is there anything I can do to help her like get a dehumidifier?

I also want to ask if my tortoise looks healthy and there's anything wrong with her shell

Looks nice and smooth to me

Are there supposed to be little cracks around the plates tho?

This is a healthy looking russian tort, nothing wrong with its shell. The 'bumpiness' is indicative of a wild caught tortoise, as most russians are unfortunately.

You'd be hard pressed to find a Russian tortoise without some kind of "character" in the shell somewhere.
They're a very rough and tough species.
