Check out the incredible detail on these pencil illustrations, by Japanese artist Kohei Ohmori.
The insanely fine tuned nuances of the bolt and its metal threads, the lighting highlight and shadows that feel impossible to draw by hand.
The self taught artist is prolific, and showcases his work on Instagram, which ranges from portraits to still life, and he dedicates himself fully to the pieces, spending upwards of 280 hours on a single illustration.
