Well, you’re writing about someone who only published his magnum opus under duress. So, you’re in good company. It will improve once you incorporate feedback from sympathetic attentive readers. I understand a writers journey is a lonely one. It is introspective. Now is the time for new voices on the text. You don’t have to heed all of them. I’m certain none of this is new to you. Nonetheless it bares repeating. I’d like one day to read the finished product.
