@DWN024ShadowMan I first try to come up with colors that I wanna use, and then come up with facial features. Then I try to think of things I like, and then put it into an outfit. I love winter inspired clothes with fluff, and Pichu's ears are really cute (and remind me of this one drawing i did of it :)). I also like buttons and the baggy oversized sleeve style.
But that's my preference! It's completely up to you on how you'd like to design your persona! Don't forget that it has to reflect you somehow! Personality wise, or even physical features you have irl! (NO, I DON'T HAVE PINK HAIR NOR YELLOW EYES, BUT MY SKIN IS A TAN)
