Thank you all for the response.
@Figment - This is valuable advice. You are right in pointing out that the clouds are flat. Please could anyone tell me why is it so? In the same setting as this one, how could the clouds have been more 3D?
The edited image does look better. Really appreciate your effort.
@Photog - Thanks a lot for your suggestions. Actually I deliberately shot just a pole as the foreground.. looked interesting. But you are right as it doesnt really catch the attention of the eye.
@TamiyaGuy - Well i did not know much about composition when i took this shot. Just a lucky chance

Thank you for your critique.
