Think about the photo before and after, never during. The secret is to take your time. You mustn't go too fast. The subject must forget about you. Then, however, you must be very quick.
Henri Cartier-Bresson
Very nice capture of a sad reality in our society. I suggest that you try a leveling crop or rotation of the photo so the bars are level in the horizontial position.
Awesome shot. A bit confusing at first, till i realized there was a big and a little monkey, not just one big deformed one. Keep it up!
