It’s not supposed to be blood… it’s spray paint. But that brings up a good point that I should change the color then to avoid further confusion.
As for the meaning, it really doesn’t directly have to do with religion. It represents freedom of thought and for everyone to think for themselves. Personal integrity, and for others to not define someone’s morals.
I don’t claim to be an artist and I’m sure it could be better. I’ll welcome any ideas too.
