to my eyes... your tank seems awfully large for your ball python. i would cover the ends (as you have the back covered). i'd also change your log hide. it's important to give balls two identical snug hides. they should be able to feel their body on all sides of the hide.
this creates a safe environment and when they feel safe, they can be more active, have fewer (if any) feeding issues and generally be a much happier snake. (if indeed happiness is something they even experience)
