Sorry Shuuun, this image is not working all that well for me. The sign and post it is attached too are much to centred in the image and that tends to give a very uninteresting composition. I also find the shot a bit too simple; it needs some more context.
Yes, that was what in my mind; i thought of the sign post to be left or right and an extra something like an eagle in flight on the bigger part of the two....
I think if it was tilted to the left 45 or 50 degrees it would increase interest. (I tried it.) You can then copy and paste vertical little ones floating in the background. You can get pretty imaginative with this image.
