Then in the future, you will mention the artist and work that inspired you, in a proper manner. I do not require you to use full APA-formatted citations for a drawing, but flipping an image over and adding a few bits in front of it is NOT enough to make it your own.
I actually like the sound of their being descended from rogue deities in your lore. Your word choice of "disease" will definitely lose you points with Maverick, but as long as you don't start lazily mixing in zombie or vampire lore, you should avoid her wrath. Hopefully.
Very well, and I will allow for the fact that you made it the character's first name instead of his surname. However, you need to be more careful with listing sources and crediting inspiration. It's not that much effort to add a link or even a brief "shoutout," but failing to do so can get you sued or fined if you're not careful. Not to mention if you plan to go to college, where plagiarism can ruin your grades or even get you expelled.
Drawing inspiration from another artist is not a crime, but taking credit for their work is. Even done without malice or intent to steal, denying an artist credit is to deny them their livelihood, which is a bad habit for anyone to get into. Remember this.
