Who was the korean artist who painted a girl on a speedbike going through a forest over a small area of water at least over 2+ years ago? He painted in a way which caused a unique effect (colors blending in to each other and a lot of texture/depth to the brushstrokes) and was at a high level of mastery
He did a livestream and drew a portrait of a girl from memory as detailed as his other work and in around 4 hours
His artstation was always posted here and was the most popular way of viewing his work, if you saw something you would know if he had painted it or not
