Author has written 5 stories for Hawaii Five-0.
I am a first-time fanfiction writer and it's a continual learning process.
I have one Hawaii Five-0 story: a series titled "My Father's Shadow" (Parts 1, 2, and 3 are complete and Part 4 is a WIP).
Other than this hobby, I enjoy photography and traveling.
Lessons learned as a writer and/or advice from one writer to the next:
1) Quality over quantity: Instead of writing many stories with little to no plotline and/or many grammar mistakes, focus instead on ONE storyline and take the time to improve as a writer. I am not saying that my writing is perfect - no one's is - but I think readers appreciate a story more if you actually spend some time on improving your writing style and sticking to your plotline. You may claim to just be writing for yourself but, personally, if you are posting your writing for others to read then, on some level, you are writing for others as well. Additionally, if you post a chapter/story that is extremely short (say, 300 - 500 words) and 2/3 of that is full of grammatical and spelling errors, please consider getting a beta reader! Take the time to improve and your readers will appreciate you and your story more.
2) Research, research, research. If you are going to stick to timelines already established in canon, then please, please, please, do your research. Don't make a canon character's birthday in August if the character's birthday is actually in March. If you're going to write a story in which a canon character now has children please make sure the children's birthdates make sense with the canon timeline. Research also comes in handy when you start writing about a place you've never been to... more likely than not you have readers who have been to that place and they will quickly pick up on the fact that you haven't if you did not do your research first. Along the same lines: if you are naming a location where a certain scene/conversation is taking place, please make sure it is a real place. For example, the city is called "Hong Kong" NOT "Kong Hong" and "Manila" is NOT "Manillo".
3) Have fun with your writing and stay true to your plot for the story. Not every reader will like every single word you write but that's okay. Don't compromise yourself or your story to satisfy the wants of one or two readers.
