I would look into getting some cork tunnels or tubes (I prefer the tunnels as hams are less likely to just block them with substrate & you can just lift them up to check underneath.
Bendy bridges always look natural so make full use of those, coconut hides are good too.
Depending on which species you have you could make a sand area but try not to take up too much of the cage space with that.
Lots of deep substrate too.
You can get wooden wheels too which look really nice but you need to get a good quality one as some of the cheeper bark type ones aren't so good & wood does need to be painted with plastikote water based enamel paint before use.
A good sized wooden house would look nice too.
