Nothing in the first picture looks natural to me, I don't know what else to say really. You just missed the mark on the shot completely, whatever message could have been conveyed through this shot gets shattered by the girl there, at least the way she's dressed. Doesn't fit, at all. The second shot is better, but the flag sort of feels out of place too. I don't know, I just don't think selective coloring works for these shots.
