kl is an amateur artist from Canada. She has become extremely popular with both Japanese and international audiences. Her birthday is on June 17th, she started art in 2001 at age 11, she just graduated from high school, and her sister is kurot, another very popular artist. She is fluent in English and knows a bit of Japanese.
Her style is unique in that it has a very high level of completion and looks like official art almost all of the time. She uses vibrant colours, clean, fine lines, solid shading, and sharp shadows. However, she also tries out different styles sometimes, and becomes extremely successful in executing techniques she doesn’t often use. Her output rate is also incredibly high. At Pixiv she sometimes posts a few pictures at once and they all end up on the daily rankings, which is incredible. Despite how fast she draws, all of her pictures look high quality, even if it’s done with limited tools like on Tegaki or drawr. She also has a moe-fied version of herself named kl-chan, with pink hair and pigtails.
Other things she has done besides art is make tegaki videos, most notably one called Regret Message about Nunally from Code Geass, and if you check out her Livejournal, you’ll find some amusing .gif animations as well.
