KU YONBAI
ARTIST | LIVE2D RIGGER | CHARACTER ILLUSTRATOR | CHARACTER DESIGNER
Hi, I'm Ku Yonbai.I'm an artist who enjoys working on a variety of projects from designing characters for vtubers, illustrating for music videos and occasionally animating for others. You can check my contributions on YouTube.Working on projects for others, whether it be illustrating, animating or both is something I'm extremely passionate about (in some ways, more than my own personal projects). Especially if I get the chance to get to befriend my clients for us to bounce ideas off of each other more comfortably!As a person with many hobbies, I also create my own content as a streamer and cover artist on Twitch and YouTube under the name FourExNine to separate my professional work and my personal work.Feel free to hire me for anything relating to illustrations and animation even if it isn't in my service list!
I'm also open to art trades as payment! (Must be for Commercial Use)
