Seems like just a bunch of adjustments layers + c4ds thrown together, not that good for a tut imo. It's too bright, add some contrast.
Slasher kinda said it. I think even that pink is too much, I'd remove it above the render a little bit. It is too much. And the background buildings seem a little small if you consider your render.
It looks like some of his head was erased, it looks weird. It's not a bad sig, but it needs more contrast
if you add the render or stock again play with b. modes ,chuck on a b/w gradient map add a light source should be better IMO
