Okay, first of all
Make the skin, your favorite flavor of candy
Make the hair, the color of your favorite item you have (you can use multiple colors!)
If you like day, add glitter or sparkle to the hair
If you like night, add freckles
If you like dawn/dusk, add earrings
If you have a pet, add ears and tail
If you do not have a pet, add wings
And the rest is really up to you! Such as the gender and the clothes, I might make mine and post it in a few minutes!
