Pheno is right. This piece shall pass.
Thinking about this piece, the peace symbol is opposite to war, the smiley face is opposite to hate, and the heart is opposite to intolerance? Idk, just examining it. I guess I see the symbols meaning different than the challenge sees them.
All the icons here are a single color, though! The challenge doesn't say it has to only be comprised of those images.
Interesting concept though ;)
I didn't know you can only use one color for each symbol, so i suppose this cannot belong to the weekly challenge.
