if the hides are the right size, enclosures cannot be too big. Never worry about a too big enclosure size if you provide nice hides and the right husbandry.
About the enclosure size.... in Germany we actually have laws governing minimum size for enclosures for python regius, to condense them all down into one sentence.... There should be a climbing option for the snake, and (if you take out everything) the body length of the snake should not be larger than the diagonal of the ground surface. But then, if you follow that to the letter, your snake has a 5 star enclosure, these laws are a bit over the top and dont really allow for rack systems. Because of the laws breeders use modular terrariums, basically huge plastic bricks that can be stacked, with a glass front and heating, equipped with two appropriate hides and climbing opportunities. Its BP paradise, but makes keeping several and/or breeding them really tough.
Anyway, a BP can be happy if temperature and humidity are right, if the feeding shedule is good, they dont need much space. But more space and more hiding places are a positive if done right.
EDIT: the enclosure directly in the post above mine.... How the heck do you keep the humidity up in that? Sorry, it just looks very dry. Did you soak the terracotta flowerpot things by submerging them in water? You must soak them once before use, otherwise they suck up moisture like crazy.
