Oh hey, a two-for-one. Was looking for the source of which the blonde was traced (because it's this "artist", of course it is traced), turns out the orange-haired girl in the front is from the same picture: post #3592914.

Tagging as derivative work, not sure if I should set this as a child of the other one though as I'm not sure if a post can have multiple parents if someone finds the source of the other characters.

*Edit* Oh baby, a triple! The source of the background is post #2858666, the same as the one they used (and actually credited, by the gods!) in post #3565122.

*More Edit* Another piece of the puzzle down, the girl on the left is traced from post #716270.

In addition, I noticed shortly after calling out the first two traced characters that the mouths and eyes of the brunette, blonde and orange-haired girl (and possibly the eye of the pink-haired girl) seem to be close to, if not entirely, identical... Are all the facial features just copy-pasted from somewhere else too?

*MOAR* Not a 1:1 trace, but the blue-haired girl is probably traced from post #2067289.
