Really, Better Call Saul and Breaking Bad are really Mike's story, let's be honest. They guy is so dark, yet so damn likeable at the same time. That's some weird writing/acting/directing voodoo right there.
I was originally going to paint in the pixelation instead of post-processing, as something of an in-joke towards when it bizarrely happened in Breaking Bad, but it looked crap. So instead I did it in post using Krita and picked a level of pixelation where it was *just* on the cusp of being totally pointless.
