i'm gonna boil my review of your last 2 podcasts here, but i really saw some similarities between both so i think that applies.
basically, the voice and the sound editing has decent quality for a podcast when comparing it to other, more developed podcasters like the ones that were in the NG Summerfest. in my honest opinion I'd try taking that buzzing out.
since you're speaking out of your mind i'd recommend you try making up a rough script on what you should talk about so you sound more fluid without that many awkward pauses, or practice talking to yourself, focus in making your pauses more natural
your topics aren't something i'll touch since like what you said they're your own artistic expression, but to be perfectly honest i like what you talk about especially since i've been going through depression for a while. so really just do what you like. but i reccommend you add a little more variety in what you talk about if you're gonna attract a variety of listeners
anyways i hope you get better (both in NG and irl) and that people get to hear you, i think you have a lot of potential, cheers lad
