That looks great. I'd recommend locating one perch much higher in the corner of the cage so that when the bird sits on it the ceiling of the cage is only a few inches above its head. Birds really appreciate a high perch, especially for roosting at night.
I'd make sure to be very watchful of that thick, braided rope holding up the coconuts. If it gets too frayed it could become a risk for entangling your bird's toes or feet. Also make sure birds are never ingesting string of any type.
One thing I started doing recently for my CAG is hanging large, rectangular grass mats sold for hamsters, guinea pigs and rabbits in her cage. I hang one lengthwise from the ceiling of the cage a few inches away from a perch to create a screened-off area for my bird to retreat to. She LOVES it. I hang a second one on the side of the cage next to a perch. The mats create more privacy for the bird so they're not exposed all of the time. This can be especially important when their cage is located near a window. (My CAG is near a window.)
One toy my CAG loves is the rubber foraging balls with a bell in the middle and a metal chain. I hang one from the ceiling free of obstruction and my CAG grabs onto it from the side or bottom and swings and flaps around. I highly recommend them.
Good luck.
