I am new here too! I hope i can help a little bit.
I like how high the bedding is, she must love to burrow
The only thing i would suggest is adding more hideouts as i only see two. Maybe some more toys too? I am no expert in cages but that is what i immeadiately see, she just needs toys and probably more hides.
EDIT: I forgot to ask why her leg was swollen? Is she using a wired wheel?
