Kotake (コタケ) has an old-school manga style that you don’t come across too often anymore. Their already flat coloring is done with shades that mostly stay around the same value, creating low contrast images with no element coming any more forward than another. This style forces you to churn through the entire picture, spending time with all parts of the relatively detailed line-work.
Something about Kotake’s characters gives me a strong sense that they are or once were alive — something about them seems very real. When I look through their art, it feels like I am looking through a picture album full of memories, or perhaps something more intimate.
