LOVE IT
It seems to me that she just kill someone that made her suffer...like...someone who rape her or something, and in a certain way she is happy that the nightmare is over but she is also consumed by the sorrow and the thoughts of what she just did...that's why it looks so happy and obscure at the same time. But regardless of how I interpreted this piece and what you were trying to express, there's not doubt that this is a magnificent job. I love it and I really really hope to see more of your work soon, kudos sir... kudos.
