DA Member Kimmo Oja has a knack for heavily detailed black and white drawings with the use of a single marker or pen. What really caught my attention are the drawings where he experiments with yin and yang, black and white, good and bad, day and night..I just love how his nature-themed drawings efortlessly flow within the confines of this iconic imagery. The universal symbol is clearly noticable as a whole, while still maintaining his own unique style within the shape. Check out more of Kimmo Oja's artwork by following him on DA and instagram!
