Chapter Five of Half Blood Prince. An excess of phlem.
I chose to do the scene where Arthur comes home from work after Harry has arrived at the Burrow late at night. That's the Weasley's Clock in the foreground (in the laundry basket), with all the hands pointing at 'Mortal Peril.'
Copic marker, gouache and watercolour.
The original art is for sale if anyone is interested. :~)
