I have found the original artist for the picture. Name of WolfRoad. I have also talked with this artist, since they are a friend, and they have confessed and removed the stolen piece. I can confirm that the newly uploaded piece is their own art and that they will only upload their own art from now on. Thank you for bringing this information to the light.
Thank you too for warning the original artist! I would have been searching for hours to find it by myself And that's good to hear, I'm glad I was useful ^^
