I'm always tuned off by artist who claim about *their* art that "no other artistic style demands so much of an artist. " Feh. That's poppy-cock no matter *who* says it.
A damn fine example of photo-realism, but I'm afraid I'm one of those painters who generaly dismiss photo-realism of this degree as being more or less pointless. I'll agree it's a great way to hone skills, but a dancer generally doesn't post vids on You Tube of themselves doing crunches to hone their abs. (Although at least there'd be hubba-hubba value to that
)
