I darkened the edges, by the Master's hair, taking the tortilla to the level of charcoal.

Then I darkened other areas, like the collar on the left side of the tortilla, and brought a little more shadow to the right side of the face.

Careful, careful.  Must remain calm.  I kept in mind that the tortilla was so hot that it would actually keep turning brown for a few seconds after I took the heat gun away.  But it was not easy maintaining control, because tonight, like so many other nights making Miracle Tortillas, I was drunk.
