"Lively Lunchtime" By Ian Chase
Paint Tool SAI, approximately 42 hours (judging by the number of episodes streamed while working).
Who can say no to schoolgirls and tentacles having a rowdy good time together? I've been working on TB illustrations for my fan expansion, but this took things to a new level of complexity. I'm impressed that the Takoashi University girls are so iconic that I can make them identifiable with only their hair and socks at times.
