Well art scenes and splashes do take up a lot of work and time. There are lots of people who can’t afford art and taking an opportunity simply as reading a story is like a huge reward, so I would personally expect a lot of requests. This actually might be overwhelming too. Think about it for a second, there’s this artist, not mentioning her name but you might know who I’m talking about. Where she opened up a shop and she does semi-realism/realism art style and she had to close because of all the art requests piling up in a very short amount of time. With this, you might always be busy and might not have the time to update your story. Either you can limit 1 art per person or something like this, or dedicate to only doing specifically 1 thing per person along with the limit. And of course like you said, you may need to close and open, and close and open…That’s what I would do. Like I’ll make every person 1 profile picture if you purchase 5 gems, and read my story with proof and so on. I don’t know this is just an example
Not to mention your a very talented artist, who wouldn’t take this opportunity?
