Isn't that sky dreadful?
A silhouette has to have somethiong to make it pop, and by definition it can't be the silhouetted element. The sky is so dull that the whole tone of the image is just dreary. Sorry
okay ... i like the silhouettes but with silhouettes and nothing else in the frame i would like to see some more composition work, rule of thirds or sumtin like that ... anyways interesting photo for the chellenge since it shows the essence :-)
