Ok I know it’s been said a lot and repeated by plenty of popular artists (especially on here) but. … just because an artist or writer is/was in the same fandom and you and made some stuff for it doesn’t mean you’re entitled to ask them to draw what you want. A lot of people either move on completely from interests, or find new things they’d much ratger draw because its -fun for them-.
The only time you would ever be able to ask an artist to draw something that YOU want them to be drawing, is if you’re commissioning them (or if they ask people to send in suggestions, but if they are not in a fandom anymore and do not want to draw stuff from it its up to them to decide).
So please stop. If you have tons of things you want drawn you could always draw them yourself and put in the time and effort and years of practice it took other people to learn how to scribble lines into a visually pleasing arrangement. If that isn’t an option you like though, just try and enjoy what’s there because there is plenty around to enjoy.
