Maybe it isn't in theory, but when you're just working stuff out, you're focusing on one thing at a time. Like imagine if I asked you to write an isekai manga plot from scratch on the spot and then I go "Okay, but what's the world's currency?" And when you go "Uhh... I don't know." I reply with "Dude, making up a fake currency isn't that hard."
This is how creating a character works. This is the process that has the best chance of getting what you want. Yeah, I can use the line of "You can't do better." but I've worked and/or were coworkers and/or friends with actual directors/artists/creators of animation before and THEY often can't do better. Their first drafts (unless they get lucky AND exactly know what they want) always look blank. Like, you should see some initial concept sketches for games or animations. I literally saw one for a hentai where the artist literally made fun of himself by writing the words "No thoughts, head empty" next to one of his concept drafts of his characters.
Again, which is why I said it's a rough draft and not really worth posting. You can still see her ear through the hair. This is a digital drawing, programs with layers, and you STILL see the ear AND the skull through the hair. Hell, the filename literally has the word "sketch" in it. Like something you draw on the spot when the idea hits you. That's how rough this is.
This type of reaction is exactly I also said to agree to disagree on whether something is better than nothing. If you've ever worked a job where have to make something for a customer, you'll know that, a lot of times, showing the customer the rough draft and/or incomplete thing just disappoints them or fuels complaints which just makes the whole making process harder.
