Killing Spell

I made a similar picture last year, and I decided to remake it. I made it by simply putting a green bottle (it was non-alcoholic) and pointed it towards my lamplight. Well this creates the "Avada Kedavra" spell effect, but doesn't explain the shadowy figure on the right. That's actually my finger on the side of the bottle xD yupp
poem~

Killing Spell

It's a simple thing really
Just a small mutter of words
Only two words in fact
Yet it strikes so much fear
It stops the strongest
In their tracks
It creates sadness
Everywhere
It tears people apart
Friend from ally
It is almost
Impossible to stop
It is
Avada Kedavra
