In my amateur opinion, it looks very nice... but may not be 100% idea for the snake.
My (again, amateur) suggestions would be:
1. I would scrap that half log and get another hide like the one you have... or even two smaller hides. They like tight hides, and if both hides are identical, they don't have to choose one hide over the other one at different temperatures.
2. Maybe put some scenic paper on two or three sides of the tank. Something like you'd put around the back of a fish tank. They make desert/forest ones too... or just use some dark construction paper. That is a fairly high looking tank, so whatever you can do to make it feel "smaller" inside, will make the snake more at ease.
