Hey man, the weapons look like it's something from a game so I don't think it'd really be a problem. It's kind of like having a minecraft pickaxe or stuff like that in my opinion..
Lol I just remembered, I drew on my lab folder out of boredom.
I drew a gun in one side, and my friends face in the other on different days.
my teacher told the principal, so had to go there and explain. LOL
