I like the border. I think you cropped to close to the right edge of the white sign though - it almost touches the border at the top-right. An equal gap on bottom, right and top of the sign would be good. Colour and focus is good - short DOF really make the white sign the focal point for my eyes. Of course it's not really a road sign, but I guess you saw it on a road so I'll let that one pass.
Nice signs and nice photo. Nice colors and focus and composition. But I don't see any "street signs" to meet the challenge with, and meeting the challenge is half of the project. It's a shame because this really is a good photo.
not only are you showing a sign where children were used for something they have no idea about, which is wrong, dead wrong, but this isn't a road sign...it's just propaganda. go hug saddam. if there were negative numbers i would give them
