Portrait, using window light

An attempt at an available light portrait (indoor subjects seem the most likely fare at the moment given the UK weather).
Just out of shot the subject is holding a white piece of paper as a reflector, which lightens his left side. He also appears to be practising a thespian mischievous half-smile.
Manual focus, aperture priority.

Anyway, Jane Bown or Herb Ritts needn't lose any sleep.
