Hi, congrats on your first snake. One thing I would change is to put some sort of background picture like aquariums use to provide some privacy. Snakes like to feel secluded.
It is always best to have two identical hides. The type of log you have are not the best choice. They are open on each end and dont supply the privacy they need. They are also hard to clean when pooped on.
Hot side temps shouldn't be over 90. Cool side at 78-80.
Other than that, it seems like you've done your homework.
I'm sure others will chime in also. Best of luck to you.
