Oka, a 43-year-old artist from Aichi Prefecture, Japan, can paint incredibly realistic portraits that people often confuse with either real-life photography or a picture created using Computer-Generated Imagery (CGI).
It takes a lot of hard work to make such intricate masterpieces, which is why Oka takes several days to more than half a month to finish one piece. One of the pictures below – the woman in a kimono – took 20 days to finish.
Oka is also very good with using colored pencils and markers for drawing realistic-looking artwork. Take these few, for example, they all look like they were taken using a camera with a black and white filter.
