Seriously though, I'm a guy with no skin in this game, with 40 minutes of free time. Imagine if I were this bishop, a man who wanted to be consecrated by this bishop, or a man who worked for one of these. I could obviously do much better.
I'm not even a Photoshop expert, but I know a few tricks. But even so, I know that I could do much better if I had a few more hours to spend on it. I could make it quite believable.
