Possibly get a different plant too. Those are safe plants but it is taking up a lot of space in your cage and isn't providing much climbing area. I would get a ficus or umbrella plant. Unless you want to keep that one!
Looking good. If I would improve something it would be more bend a branch. You can hang them from the top of the cage using sime twist ties. Just make a loop on the branch and hang them making sure to wrap around the plant and secure them on the soil. Easy and works great
