Cyberman Ages

I think this has to be my biggest most ambitious pencil drawing to date. It depicts all 7 versions of the cybermen from Doctor Who over the years. So much little bits of detail to add to the robots it seemed to take forever.

Size 24"x19"
Mechanical pencils, B, 2B, 0.3, 0.5, 0.7 and 7B pencil for heavy black bit.
Took 3-4 weeks on and off, about 30+ hours.
