It's Hatsune Miku's 15th Anniversay, at least in Japan time. I discovered Vocaloid a few years ago through The Caligula Effect, and have enjoyed it since.
I really like the two designs of Racing Miku 2022 , so I drew that. #初音ミク15th#初音ミク
I was playing around sketching on pulp and cotton paper side by side, and I ended up drawing Chisato from Lycoris Recoil at the bottom of the page, with some variation ((bad))
Round 16 is too big for the eye details. I also like the sponged off background on the pulp paper.
