Can I sell my art with living beings on it which I made in a time I didn't know it wasn't halal?

In the past, I used to draw a lot of Anime characters and living beings, but now, Alhamdulillah, I have stopped that because I know that it is not permissible. Can I sell my art with living beings on it, since its not something I would like to throw away? If I do so, would I make a sin for providing others with such pictures to hang in their rooms, where no angels come? If it is a sin to sell something like that, Ii would definitely burn them. I just need an evidence hadith or Quran verse where it says that.
