as long as you can give them a water bowl they can climb into and soak themselves you dont need as high humidity,they love to soak
for long periods at a time a water dish that is not big enough for them will either get moved all over the place or turned upside down.

I would also give them a hot spot for thermo regulation they can do this far easier when they can just move from one side to the other. Your humidity is a bit high for my liking but without actually looking at your setup in person its hard to say if it is an issue.

This is a pic of one of mine and his water bath as I call it lol




what your snake is showing looks like dry scales to me I agree with aahhmn there.

remember they can get large ........



but they can be cute too.....




but dont get complacent as they are sneaky at times always watching as only they can ...



full of character the bloods far more than the average ball IMO hissing and puffing and bluffing although sometimes the bluff aint a bluff ....



very nice snake by the way I would not be worried from what I can see. Monitor the situation and see if it changes with slight mods.
