What character, the pose they'll be in, the main color theme, and any preferably abstract background elements, and of course any other kind of specifications that are important. But this all depends on the complexity of the drawing I'm being payed for. Also, no NSFW or Kink related art, ship art, real people, furries, or mechas. I am okay with gore though, to an extent, I do have limitations on it. Also, will be willimg to do things like youtube thumbnails, but the price would have to be negotiated depending on its complexity.
