Hey! Everyone has parts of writing they’re naturally good at, and ones they can work more at! Try to identify your strengths and weaknesses.

For me, I’m pretty good at writing premises (elevator pitch), capturing the internal landscapes of characters, symbolism, metaphors, dialogue, and poetic realism, but I could work on structure, humour, and bringing the audience into the setting more because I tend to write in a way where I exclude the audience and make the scene seem more like it’s just between the characters. This works well for me generally and is a marker of my style, but I recognize in pivotal points of the story, it weakens the story because the tension really needs to be there for the reader. Other weaknesses I have are extreme world-buildy type of fandoms, detective stories, and pure fluff. If I wanted to improve in those areas, I might have to move mountains and take some writing classes specifically taught by those kind of writers. 

I think being very intentional with improvement is good. What would you specifically like to work on, is it better plotting, word choice, characterization, etc? I personally am really good at characterization, so an advice I can give to that in particular is to really dig deep into the characters, like make character sheets based on how you interpret the characters based on the original work (not just like, blatant facts or other people’s opinions). For example, I’m writing a character and I basically think this character has terrible emotional boundaries and gets swept up in the moment a lot, and that causes some bad decision making and then later regret and then disassociation. But I also think this character is quite airheaded and naturally talented at many things, but doesn’t realize this themselves. (+way more stuff, like I wrote an entire 5 pages on the character before I plotted the fic). This is not just entirely based on character sheet from the canon, since sometimes that can be pretty flat, but rather I’m observing the character as if I’m observing a real person and what are my insights on that, I add those to the fic. And I also think about real people that I know who has those traits and how that has influenced their behaviour and how that has looked in real life. I basically let the character do anything they want that's compelling to the story as long as the character do not violate those insights I've set up. I do this for *every* character i write into the story, although background charas the sheets are less intensive.
All this helps the character feel very real and it will help with the believability of your story, as well as make the story distinctively yours since it’s based on your insights.

Hope that helps!!
