Ok, can everybody stop replying to this topic!?
Most of the people here say that the render is bland, like the background, but I think I doesn't matter. I think @tutibrave made this render just to showcase his Rig. Most of the time when you showcase a model or rig the background and visuals don't have to look fancy, because you are supposed to be paying attention to the rig, not the background and visuals.
So @tutibrave just so this doesn't happen again, if you are showcasing a rig you made, when you are making a post or topic put "showcase" in the tags or title so people won't be confused when you make a render like this.
