How good at drawing are you?
As in, if we asked you to draw us a horse, would you be able to conjure up something of equine proportions, or a four-legged accident that could readily be a cow?
Either way, we assure you your sketching skills are woefully lacking when compared to one Chuan-Bin Chung.
Chung is a visual design lecturer at Shu-Te University in Kaohsiung, southern Taiwan, with a specialism in the human anatomy. Whether working on chalk boards or white boards, his creations are the sort of thing we'd happily spend good money to gawp at in a stuffy art gallery. He's even got a YouTube channel dedicated to his lectures.
Assembled below are some of his most awe inspiring works. We'd never clean the board ever again...
