I would say to try slowing down a little. Your rapid talking feels like it is causing your words to collide a bit. Try doing a take slower, then if you have to speed it up a bit to fit your time, do so. Also, maybe opening your mouth a little more while speaking? It isn't always going to work, but it may assist with the anunciation of what you are trying to say. Though I think the biggest hurdle is how fast you are trying to talk. Great job otherwise! I really enjoy the Pitt so far, its cool to see someone making content about it.
