Interesting and very skillfully done: Whether it's real make-up or digital make-up is almost a philosophical question now, as you may not be able to tell the difference.
Whether we like it or not is of course a different matter. If I were a real make-up artist, I would probably choose a less severe alteration of the model's look - if my personal taste were guiding it. Similarly, I'd probably apply a lot less digitally.
but being able to do it would be cool! Not every photo is "serious" - if I could take a photo of my kids and make them look like zombies with digital make-up, that would be fun! If I could do that to a photo of my wife it would be fun and painful!
Any tool that expands our creative options when it comes to producing images is a tool I welcome.
