Of course trying to perfectly emulate another human at painting is going to be virtually impossible. You could try and emulate my 5-year-old's art, but I could then demonstrate with a team of forensic analysts that you've failed to exactly emulate some of the nuances that my 5-year-old displays in his art. Will you then appreciate the kind of work my 5-year-old produces when you realize how difficult it is to perfectly emulate him?
