It's not slapdash; his work contains a lot of detail and beautiful colours, harmoniously painted. There is a sly wit to his colour schemes: a blue jay against a hot lime green background. It's political and environmental, but in the most subtle manner.
This great bustard is a 3 metre high painting in London's east end. This bird was hunted to extinction in Britain by 1832 but has recently been re-introduced and is living wild in England for the first time in 180 years.
