Have to say the viv is lovely... and so is the snake.
Definitely a normal, but what nice flames and coloration on her/him! Gorgeous animal.
I use tubs so I am not a pro on how to maintain a tank. Ideally you just need to watch your temps and humidity. 90 on the hot end and 80 on the cool end. And a humidity of 60%. The trouble spots will be your overheard light, and your open mesh lid... those will suck your humidity.
And watch the aspen it can mould quickly.
Welcome to BPs and welcome to the site.

EDIT: the best gauge will be the snake. If he is eating, shedding, and being a BP... then you are doing something right.
