Artist: Bamboo Love

Bamboo Love does amazingly large and detailed drawings which he recently exhibited in a show called "Japanese Graffiti". From the site:

If you ask people the art as the quality or the amount, the majority should answer "quality".
That is the high-quality products is selected.
However, I do not think the high-quality products are good things.
Because, sometimes a huge amount of quantity makes quality.
Only one line is a "scrawl", however it turns to the "art" when building up the lines, and the lines beyond a threshold.
