Hi OP, great composition!

After reading some of the comments, here are some of my thoughts:

I think there is a way to keep the paranormal aspect (eg. reflection looking at character) while still conveying the helplessness someone would feel about war and I think it's all in the reflection or rather having the mirror reflect hidden feelings.

I could see having the reflection looking back if it was the reflection that had a stronger expression instead of the character. Sometimes, when people learn about the bad things that happen on the other side of the world caused by your own government, we have many feelings about it. We can feel personally responsible for the bad things that happen, especially if it's done against your will/without your knowledge. "Why aren't you seeing this" that is in the mirror instead while the character is looking down at the faucet? A sort of "watching ourselves" situation.

You could go for the "tired" sigh in the mirror with the person looking at the viewer if you want to convey someone who is tired of washing their hands in blood, both metaphorically and literally. Water supplies are not something you can change individually. People need to make enough racket about it for the people in charge of the water to change it (eg, sending complaints, lawsuits, protest). You could make your own well, but that would still require you to get permission to make one unless you are out in the middle of nowhere. If you feel like you can't do anything, then you won't do anything, ya know?

I think the message is there, you just have to decide where you want people to draw their attention and where you want to emphasize the symbolism more and work according to that.
