if you dont mind a suggestion or two: If you do mind just ignore this. Sometimes the best thing you can for a shot you see is to change the angle of view before you shoot it. Both of these would have been much better shots if the angle of view was different.
Number one would have been a more dramatic shot if you had stood close to the wall and shot it at an oblique angle, The box would have showed in an almot squared off u shape because of the forced perspective.
On the poles same thing. If you had taken about one giant step to either side the line of poles would have led you into the frame of the picture, rather than cutting it in half.
I wish I had something to show you but I reall cant think of anything off hand. Maybe someone else can. The texture on the concrete wall in number one is good and you wouldn't have lost that with a strong oblique angle on the box.
