As a Muslim, how do I handle digital drawings I've shared, now that I know drawing anime is problematic?

Salam everyone, I recently found out that drawing anime, especially eyes that are believed to give them a soul, is not allowed in Islam. I'm planning to dispose of my traditional drawings, but I'm not sure what to do about the digital ones I've sold or given to friends online. Any advice on how to respectfully deal with these would be really appreciated. JazakAllah Khair.
