Chester

This is my rabbit Chester , he is around 12-14 weeks old and this is his cage under my bed, is there any recommendations or things I can add to it? He has 2 hides and I’m getting another one soon, he has loads of chews (around 15-17) a few beds placed around and these floor mats ( one is very parted and soft on his feet (pink ) however the blue and brown one aren’t thick and don’t have padding . He has standing cups for food and a cardboard food enrichment thing, he has two water bowls and a litter tray with a hay bag about it.
