Hi hun! ^^
I just to see that people is telling you that you should delete the re-colored pictures and maybe you're thinking they're removed, but they don't
You only removed them from your feature gallery, but they still appear. Maybe you don't know how to delete them, cause you're a new user, so you only have to follow this steps:
Gallery>>>All>>>(click at the picture)>>>Delete (next to the 'Edit' button)>>>Cleaning up deviation submissions
You have to follow this steps to remove the artwork correctly
I hope this helps you ^^
