Black Vocaloids

I decided to draw some Black Vocaloids! I've been doodling Black Miku. I've seen a her name spelled Maka but I like Mika. I love the afro poofs on her. Ren and Lin are the best I feel. I made them lighter toned and gave them blond dreads, I like the colors on them. For names I'm thinking Ray and Ln. On the bottom is Black Meiko and I just gave her soft curls( as if she permed her hair) and changed her outfit a bit. I think her name will be Meika. Should I do a Black Rock Shooter and other vocaloids?
