Speedway!

*disclaimer: this is based on what’s worked for me, aka an artist that likes to make comics/storyboards. so this advice is directed at people who do that

you can do things like this:

Which is fun! Character sheets like this are great, especially for personal reference! But frankly, I don’t think most people engage with this (at least I personally don’t). You could have the coolest character in the world, but it will be harder for most people to feel invested when they’re presented so neutrally like this.

My main piece of advice is: get better at writing.

That might sound harsh when said like that, but let me explain what I mean! (Not trying to imply you’re bad at writing either!)

What I tend to do is just throw characters into situations with as little handholding as I can. Give enough context that readers can follow along, but don’t feel like they’re being explained to.

what can you learn about the characters through their designs alone? (age, personality, economic status, occupation, etc)

what can you learn about the characters’ relationship though their interactions alone? (are they close? familial? romantic? is there hostility? are they tense/relaxed?)

what are the characters currently doing? what were they doing previously (how long have they been talking)? what are they going to do next? can you convey this without dialogue?

how do they feel about what they are doing? are they content? focused? over/understimulated? would they rather be doing something else?

where are they? does it matter? would establishing a setting in at least one panel clarify the scene? is there anything in the enviroment that could tell some of the story?

what time of day is it? what time of year is it? what is the weather like?

Now, with all this in mind, I'm going to give you another example. I'm going to use completely brand new characters for the sake of the experiment, so you won't have any bias (aka I can’t use Protagonist from above, since you already know all about him).

Did this get more of an emotional response from you than the first example? Why do you think so? Who are these characters? How do they know each other? What else can you infer about them? What happened? Who is "she"?

Now, you don't have to actually answer all those questions. But think about them! You can tell people a whole lot about your characters without ever showing them a list of their likes and dislikes.

Obviously, comics aren't the only way to get people invested in your original characters! But regardless, easily digestible formats will grab people's attention faster than huge blocks of text, and comics are a lot less work than doing wholeass storyboards.
