I don't listen much to Vocaloid, but I love the concept of them! I'm just so amazed by it and and and I love "Heat Haze Days" too. I should prolly draw that, too, some other time. Anyway, these are my fave Vocaloid artists.
The background was spontaneous. I colored it blue, then randomly added circles, and then randomly added musical notes again. Idk, but I like it. 8D I finished this pretty quickly, using ballpoint pen, color pencils, and correction pen for highlights and the musical notes in the background. OwO
