Kim Jung Gi is an amazing comic artist who draws from his imagination with ease. He has mastered the art of drawing in fish-eye perspective, which is apparently the perspective we (as humans), see the world. I would love to be able to draw like this someday.
WARNING Kim Jung Gi does have EXPLICIT CONTENT in some sketchbook videos. You’ve been warned!
Here is a good video, although not in english, it is interesting to watch as Kim demonstrates the use of perspective, when drawing anatomy.
