It may not shock you that incredible things can be done with just pencils and paper, but the breathtakingly realistic drawings of 22-year-old Japanese artist Kohei Ohmori are bound to leave you amazed.

The Okayama-based prodigy spends more than 200 hours on each pencil drawing, and his attention to detail is strikingly evident. Thanks to carefully-placed shading, ultra-thin lines, and a remarkably steady hand, Ohmori’s black and white drawings look as if they’re going to jump right off the page. They’re so immaculate, in fact, that his Twitter audience is calling him a ‘mad genius’ and ‘insane’ over the amount of dedication he puts into his realistic artworks. His most recent effort, which has yet to be completed, depicts a shiny nut and bolt, while his ‘signature piece’ is considered to be a stunningly detailed drawing of British model Sophia Blackbrough.
