I actually like it a lot (though I dont share much of it on main/public)! but I reserve much extensive ones for works that needed such complexity in their characterisation (usually multichaptered fanfics or a series), otherwise I just wing it like gods intend it to be!

even for series/alternate universes that are very different from the canon, I'm trying to incorporate some sort of short character bio (bc I like making them) though I'm very ... perfectionist—I worked professionally as a narrative designer once after all and still does professional writing—so sometimes it just ends up being delayed a lot (mostly visual problems bc I cannot draw/render 3D 😂)

hope that satisfies your question, anon!
