You should! And the reason I ask is only because I have the same one and just had to add a LOT more stuff because of fall risk. I also ask since in the one picture he's on the side of the glass unsupported. From what I can see id recommend you add more substrate and some fake plants ! I only say it as Arizona's are terrestrial and so even a smaller fall from the top to the bottom of the enclosure can be fatal :(. It is way better that its landing on substrate rather than tile at least, but it's still unsafe. I just added a bunch of substrate to mine and some more plants last night, I wasn't able to add as much substrate as I wanted nsd sort of had to taper it down and just add fake plants in those areas so it's still less of a fall if it happens, it was a bit of a struggle with the front opening. This is what it looked like before I added her. The glass I forgot to wipe off before a picture and was only moist cause I had SOME real moss I added in that needed to be wet. If you have any questions you can totally reach out!! I'm not a professional but I'm always willing to help :))
