Thanks RonSutton, I appreciate your comment and like you I believe that the image is important. I knew that the second image was too harsh as I was applying a preset without changing any values. For the first I thought it looked flat and that's why I sought advice. I always ask myself these questions whenever I am taking photos "why am I doing it? what am I trying to say?" For me, as photography isn't a profession, all I can do is put my feelings into it.
The only editing/processing I do is to bring out what I want my photos to tell and what I want my viewers to see/focus. In this case I love the sky and clouds and I wanted to show their tranquility, their zen nature.
The photo was taken at a spur of the moment from my office window after just having lunch. That day it was raining and very overcast in the morning so instead of going out to be a photographer I had decided to go to the office and work when the afternoon weather improved (I'm still regretting going to work that day, since then the skies have either been very clear or overcast) I just got my camera out and took a quick snap. It's not in any countryside or any beautiful landscape, I just framed it so that none of the buildings show, not the American Embassy which is just behind the trees in the photo nor the ICRC HQ which is just to the right, nor the WHO HQ which is to the left.
