If you have a good art director, a good photographer, and a good CGI operator, then you can create wonderful results. If you have no time, no money, and a bad retoucher, then you can see all the ugly stuff from other campaigns.
So true, Egon. My mom, who was a self-employed fine artist for over 75 years, used to say "The secret to success is to keep your feet on the ground, your head in the clouds, your shoulder to the wheel and your nose to the grindstone. Then try to work in that position!" She would also quote Michelangelo: "If people knew how hard I have to work for my mastery, they would not think it so wonderful".
