If Hirst did not try to paint an orange accurately, no one would know he can\’t do it. But he has tried, at least I think it\’s an orange, and the poor sphere seems to float in mid air because of the clumsy circle of shadow below it. For a moment I thought this was intentional, then I realised it was a competence issue. Such issues abound. You look at a branch and it is obvious he has worked at it: equally obvious the work was wasted. At their very best these paintings lack the skill of thousands of amateur artists who paint at weekends all over Britain – and yet he can hire fools to compare him with Caravaggio.
