That's okay, But maybe just do a few takes of it and play it back to see how many times you stuff up a word, or say something wrong. Just so it sounds better for the audience. It's a good idea for a series, It will take you years to complete(literally). I wish you the best of luck and hope to see episode 2.
Also don't rush things, I don't think you did for episode 1, but I'm just saying that if you rush things it will sound terrible.
