A number of things about this:
First off, I have no idea how you got that to line up like it does. Of course, it's difficult for me to do that stuff because I have some shaky hand syndrome, but still.
Second, this is relevant to far more than just those Belgium shootings, this is relevant to every single man, woman and child in the world today, because everyone is at some point in their lives effected by violence. Not necessarily lethal violence, even verbal violence, video game violence, etcetra.
Third, One thousand three hundred thirty seven thumbs up for the little dude with the rope. The world would be such a better place if there were little dudes like him stopping the guns from firing.
Fourth, the shading is wonderful, and I like how you managed to texture the gun handle. And I don't know if anyone else has noticed this, but there is a little sad face in the small circle above the thumb joint.
Fifth, are those white things in the windows security cameras?
Sixth, you are now on my watch list.
