For most of those commenting, please, GET REAL, and watch some more episodes!
It is NOT a photography contest!! LISTEN to what is said as the judges walk round -- you'll hear that artists who paint 'from life' are that rare that the process draws a comment!! Almost everyone paints from an image on a gadget, has done for some years now.
The judges are clearly looking for that elusive quality that catches some aspect of the sitter that maybe isn't that obvious from what a simple snap would show? (dozens of shows . . .masses of comments . . .).
The ballet dancer was NOT forced at gunpoint to stand for 4 hours, was he?! And at the end, he said the only strain he felt was actually in his arm, from that pose (as in the ballet he was dressed to play in).
Do I like all the finished pics? Certainly NOT! Is it worth getting upset about? Well, this last week we saw pics by the likes of Holbein, Brusghel, and Picasso (etc). Doubtless the portarint by Picasso (of his then lover) is worth squillions, but it looked like a 5-y-o could have done it. Did I throw things at it -- no . . . .move on!
