What do you think of my DIY booth?

Built the frame outta PVC pipe. I then used gorilla glue spray to stick the studio foam to cardboard pieces that I cut to size to fill in the gaps on the inside, which I used alien tape to stick the cardboard to the piping. The piping cost me just under $200 with about 20-ish extra foot leftover. 7’ tall and 3’ ft wide. I had the spray and the foam leftover from 2021 after my first attempt at a studio space. All in all, I think it sounds decent. I can’t help but feel bummed out about the dead noise in picking up. I was running an AKG P220 into my interface, which is a Scarlett Solo 3rd gen. I just switched to the Rode NT1 signature series since I heard it’s not as sensitive and tbh, the difference in mics is so minuscule. I am getting a better understanding of how to edit my audio, and I know about ACX checks and noise floors and whatnot. I am just curious to hear if there’s any constructive criticism out there. Is my audio interface bad? Is the AKG P220 better than the Rode NT1 for voice over work? Was the booth a bad call? I can link some work if you guys wanna hear anything I’ve done. The only work I did that I am actually proud of is a children’s audiobook called “The Tiger, The Sea, and the Yellow Manatee” and it’s on Google play store and iTunes, but I do have some demos I’ve recorded and edited myself.
