Everything is fixable Seriously, just have fun with the first draft. Even if you end up scrapping the whole thing and starting again from scratch, it'll give you a solid basis. Every draft, every word is experience and progress. Keep going with it and, like I said, have fun. Use it to explore your setting and characters without stressing too much about the quality of the writing. Your stress levels will be tested enough later on; preserve them! And good luck!
