that's a nice big cage! seems about the same size as my Rhino's abode.
a few things you will want to change though:
get rid of that wheel ASAP. they are dangerous due to the wire mesh on the running surface that can catch chin toes all too easily.
put a couple shelves going side to side in the cage, or hang a hammock across the middle, half way up. if one of your chins were to slip and fall off one of the top shelves, they'd go straight to the cage bottom - a long drop for a little chin!
either move the plastic items off the top of the cage, or put a layer of fleece across the cage top as a barrier. i can see one of your chins easily chewing the bottom of that food container. i also store things on top of my cage, but have a sheet of fleece that goes across the top and down the back (also gives Rhino a little more sense of security, since all 4 sides of his cage aren't open to the room).
the metal hay ball is also dangerous - the spacing is just right for an arm or leg or head to get stuck. i'd just put the hay loose on a shelf until you can get a safer container/hay bag.
i can't quite see the cage bottom, but it looks like you have a plastic litter pan in there? i'd be switching it out for a metal or glass one. i use a metal mixing bowl for Rhino's litter pan, and other members here use the pyrex baking dishes. both work well.
other than that, looking good!
Also my futon is right next to it so I can sit and do my homework and talk to them and they got a great view of the TV!
