It’s a pretty awesome render! Unfortunately per the guidelines and rules, the scene, especially the main focus, has to be made by you and not previously made models or assets as you can see here per the rules and guidelines: Weekly Challenge Rules & Guidelines
Now because I migrated the site from an older site about a month ago not everything was migrated yet and I did forget to put the rules and guidelines here so that is my fault.
Were the shield and sword done by you? Maybe you can tweak the render to include just the sword and shield and fire and put a grave or something or something different in the render so that it is done by you. Again it’s a sick render, I would post it in the finished projects and if you still want to enter it to the Weekly Challenge, you can tweak it so that it meets the rules and guidelines. Sorry for the confusion.
