I don’t think anyone wants to police other artists’ methods. Of course people use short cuts. They use scans or project templates as guides. But you really see that as the same as sculpting part of a head and pasting photographs of the major features on the render in photoshop? Really?
Top row is prestigious. It is recognition and great advertising for the artist. I know guys on the top row that actually put it on their resumes.
This is more about honesty than anything. If he had been honest about his method, no one would complain. But also, he probably wouldn’t be up on top row.
