Interesting photo, and an interesting phrase. I feel the colours in this shot could have benifited from some attention in Post processing,. The photo appears to lack contrast, and some saturation adjustment could have made this stronger. Not sure about the presentation. I feel this would have been much more suited to the traditional motivational poster with black border, title (Trust) and the phrase underneath.....
Technically it's perfect. Nice angel of view. Still it has this snap-shot feeling, because they are neither posing, nor you know what they are watching or doing.
The message is great... but the perspective is a little strange (sorry... dont know the right word in english)... im talking about the diagonal of the line of the building when comparing to the right edge of the photo... that little unparalel sounds weird (and, again, weird is not the best word for this)
this photo lacks of a border (I'd prefer there to be one, consider it as you were writting a motivational letter and following certain rules) I think that the first part from the sentence is enough, the second doesn't fit very much for the photo
