Not bad... I'd lose the glow around Knox on the left... it's not needed. Also fade him another 10% and put the layer on "screen" mode to get the affect you're going for.
The Kofi one is good, but too sterile... unless you're going for that look. The Lion's off center a bit, and actually the wrong one, if you're going for the "Flag of Zion. I'd make it dirtier like the first one...
