Open up Paint. You see your palette? That array of bright, sickly colours? You only need to use those. Anything less vibrant will ensure that your fursona is not unique and special enough to attract attention. Also, having just one set of genitalia is so out of fashion. This year, having about three is in. And in a similar vein, if your fursona is only based on one non-human animal, get the fuck out! It needs to have a t least two, and probably human thrown in there as well. Finally, make sure your character's history is filled with all sorts of extreme bullshit that would never happen in real life but sounds good on paper (to a 12-year-old).
