Hello there!! I’m really glad you’re taking the risk of something so big as writing a book. I’ll make sure to check it out, we can support each other if you’d like. I’m assuming from your comment you already read the one I’m starting, and if not, you can check it out. I’m about to post the second chapter. As for the tips, sure thing!
1. Describe your surroundings a bit more than normal. Give the reader random descriptions to make it longer and for the reader to have a better perspective of it. It may seem weird, but it has turn out pretty well!
2. Try to describe the characters’ feelings. You shouldn’t just say “They felt scared”. You could use things like describing the effects of the feeling. “Their hands became sweaty”, “A shiver ran down their spine”, etc.
3. Try to not repeat words. Even for a name, you could use the “Black haired/blond haired girl beside her”. Like, not always repeat the name of the character. Even with things. If you placed the word “suddenly”in the last paragraph, don’t use it twice. Google has many synonyms.
4. Try to engage your readers with the start of the story or chapter. You could leave the previous chapter in a cliffhanger, that helps a lot.
Sorry if I spoke too much, but I hope it helps. I’ll be glad to read your story!
