Hyper-specific advice because I don’t see enough of this!
make your characters have inaccurate perceptions of themselves. your character might think they’re selfish but at every opportunity they act selfless. we all have blind spots so give these to your characters too! (this works best with first person pov but I’m sure you can do it in third.)
make a character’s personality trait helpful sometimes and harmful other times. impulsivity that makes them act quickly in high-stress situations which is great but it also sometimes results in the wrongchoices.
make an excel/google sheets doc for your outline. for mine i have the chapter number, the date, the character pov (since mine is first person and switches between 5 characters), a summary column, and a continuity column. my story takes place in one setting but most stories have multiple locations, so you could include a column for that, the time of day, even the moon phase (one of my wips is from the perspective of animals so that is super important for that story).
you can also use excel/sheets for keeping track of your conlang. for my animal wip i have constructed a language called Vannro and I have 300 some-odd entries into my excel doc. i have columns for the Vannro word, the English translation, etymology and derived words (for some), the part of speech, and the subject. you can easily sort in alphabetical either in English or your conlang, and also sort by excluding all entries that aren’t under the subject “derogatory” or “places” etc. I always forget what my “be” verbs are so I sort through the part of speech column so I can find “is” “was” “are” etc.
use perspective to create tension for your reader. for example, in The Blackwater Anomaly in a chapter from Rainer’s pov, we experience his nightmare, however in a later chapter from Holly’s pov, when she asks him directly, he lies and says he hasn’t experienced any nightmares. Holly doesn’t know he is lying but the audience does. I also have characters who do notget chapters from their perspective, who may or may not be lying, and so both the audience and the characters experience that anxiety and uncertainty together.
consider using deep pov. you can read some articles about it but essentially you make the audience experience the story at the same time as the character and it makes your narration more active. this can also be done in third person. this has a lot to do with “show don’t tell” (although sometimes its better to just tell). remove some “telling” words like “thought/felt/saw” and just get directly into what’s happening. instead of “Ava saw a shadow fall across her shoulder” make it “a shadow fell across her shoulder”. your reader will know who you’re talking about. this even jumps into the unreliable narrator when you change “I felt like Isaiah was blowing me off” to “Isaiah blew me off.” the former has room for doubt and makes your character seem weaker. if she thinks she’s being blown off and she’s pissed about it, make her say that! you have to make the audience believe it’s true, it makes them more invested in the character’s experiences and emotions. and then if they later find out Isaiah wasn’t really blowing them off, there was an emergency or something, both the character and the audience can feel regretful together over misreading the situation and being pissed at Isaiah. if you leave room for doubt, then your reader will just feel unsurprised during the reveal and frustrated at your character for being stupid up until then.
you don’t have to “show” everything. sometimes there’s boring parts of a narrative that no one really cares about. you can either make a break in the text to show a time skip happened when your character was driving from point a to point b or you can give a paragraph or two about the drive, just telling what happened, even include an accident on the side of the road or an unexpected and frustrating road closure. its a very mundane and relatable aspect in our lives and we don’t need to be “shown” these, we can just be told. summarize the nonessential by telling or just skip it.
