Let me give an example of how a conversation is usually written in books.
"_____, we should go to the mountains! I heard they're very pretty," ----- said eagerly.
_____ grinned. "Okay, fine, you win," they said in defeat.
It makes it less hard on the eyes in my opinion and has a better look overall.
Now for the actual words itself. I know that quality over quantity is a thing, but adding longer chapters and prologues and stuff, with more detail makes for a much more interesting book. If you use google docs, about 3-4+ pages is a chapter with like- font size 15. It makes a book a lot longer and full of more details, and in general is better for chapter books.
Also, I advise not using dialogue every few paragraphs. Only having dialogue doesn't give much to the imagination, and having more details and explanation of the mood and surrounding area brings a book to life and lets people imagine what things look like.
You might not read Wings of Fire, but imagine describing IceWings as "Usually blue and white dragons that live in the cold"
It gives no details to their wings, claws, tail, body form, abilities, NOTHING! π§
Anyways, don't take offense, these are just some *pro* tips to get you started! Have fun writing, you can always ask me questions abt writing if ur stuck and I'll see if I can help :]
