From the title I got the feeling that the big shapes were like shadows or memories of people. I love the way they dwarf the small person in the centre. For some reason I get a real sense of the solitude and smallness of the lone person in the middle too.
I really like this! how interesting, the big shape in the middle of the picture remind me of a mountain shot I've just seen going thru my deviant watch. Anyway, it really capture the attention, as do the background, with a composition that's brilliant and that still gives space to the foreground with the little silhouette that gives an idea of movement, and I just love the play of light and shadow and black and white, it's rare to find such an emotioning piece in black and white outside from photography! Yours is a brilliant work!
