Nice colors in your shot. All the lines and colors in the artwork do appear somewhat chaotic and frenzied. I think I would have preferred this shot with only the artwork showing....not the street items as well. I'm not sure how that would go with the rules, however. Still, nice find for the challenge.
I woulfd like to have seen more of the wall, and less of the sky and the hoarding above. Nevertheless it is good. The colours are bright and the perspective is well caught.
It looks very deliberate to me. It does have a "riot" of colors though. Get it? The telephone poles don't add to the composition and might have been avoided if a different angle had been used or some cropping. Aligning the bottom edge of the fence with the bottom edge of the frame might have increased the feeling of displacement.
Nice shot of chaos, but the pole on the right is distracting. Maybe crop just to the left of it and then clone out the overhead wire. Blue looks a tad oversatured in the sky, but it certainly helps bring out the colour in the wall
