Sagaki Keita’s pen and ink illustrations

I recently spotted the work of Tokyo based Artist Sagaki Keita over at thisiscolossal.com.
Sagaki uses pen and ink to illustrate well known art pieces in a doodle like fashion. The detail and humour in these pieces only become clear on close inspection.
Each of the pieces contain thousands of characters that make up the main image. You can see more work over at sagakikeita.com
