Kosuke Ikeda is a fantastic Japanese illustrator who I noticed on a visit to Hong Kong. I love his use of patterns in his drawings.

Pierre-Louis Mascia is a wonderful illustrator, his use of texture is really amazing be it typography or lace. I can’t find his own website, but I fell over his illustrations on his management’s website.
