It's been a year since then. With changing success, I was making and remaking a tutorial for this scene multiple times. Meanwhile, it was collecting virtual dust on my hard drive. So, I thought of just releasing the file. I cleaned it up (so don't worry, nodes are logically named, you won't be completely on your own with the chaos of my original frankenstein xD). I never realeased just the file, so let's see how it goes :P
PS: oh yeah, the file also include a 4k render of the Mirror Scene ^^
