Even if I submit those Pictures a single entries, they all have the common Topic of "Looks and Glances": From amused to haunted, from virtual to sad or wary. And they all belong to the genre "Street".
I did convert the Pictures into BW because they work better without the distracting Colors, because they do not add any important additional Information. The last one - the Boy behind the window - would work also in BW. As it is not a decidedly series, I left it in 4c because the red paint on his face makes it still more clear and I also like the combination of the three Basic Colors red, yellow and blue.
