ooh that's so cool! thank you haha, memories indeed!

ahh I'm not a professional, but keep in mind: less is more. for example with character design, think of something that you won't grow tired of, with not too many details but still a striking look. one or two characteristic details usually are enough (that could be an accessory like a scarf or a ribbon). the same goes for a story, it should be something that isn't over the top and has a clear plot, and a clear beginning, middle, and ending. if you have multiple characters, make sure they are distinctive enough, yet simple. the art is to find the balance between those things. what also helps when designing characters or writing a story is to take a third-person perspective and wonder how much you would like those characters if you would see them in a movie or in a book. that often helps!
