Left 4 Yandere (Linework)

I've wanted to draw something like this for a long time and this got a bit different from what I first thought a few years ago. I enjoyed when I used to play left4dead2 on pc because the big amount of mods it has, and I enjoyed using the lucky star or the vocaloid tda thing instead of playing with the unmodded characters, I still remember waiting for the entire vocaloid mod to be completed since it was being done one by one, also I thought it was really cool to play the mod maps, this picture is based of yama, i thought that was was cool. daybreak was also cool, it was nice to play with all of them.
