Caricature: Mr. Lim-The Legend Retires

Picture this: My Dad's newly retired. He's home ALL THE TIME. He's almost always on the computer.

When and where am I supposed to do this surprise portrait (coloured digitally, I might add) dedicated to his retirement?? Oh yeah, and he's a night owl.

Let's just say I spent several days and nights in a very small, cramped space in constant vigilance.
