I'm going into London tomorrow to view Mr Yeo's portraits at the National Portrait Gallery. I particularly like this one of Damian Hurst. Apparently the rubber suit is what he wore when preparing his formaldehyde specimens.
I've noticed his tendency to have the top of the frame touch the top of the sitters head. Now, whenever I take a portrait, I always make sure to either crop hard across the forehead or leave plenty of space above the head. Having the frame just touching the head appears like a mistake. But while it might annoy me, it's clearly not regarded as detrimental in any way to his works. I guess if you've mastered the 'rules' then you can ignore them. Still bugs the hell out of me, mind.
