What was it? The tail looks like a kite! Am I right? I particularly like the roof top, chimney pot with the aerial and pigeon! Have you got the end of the aerial on the original file? If you have it might have made a more complete image!
@jokristina What a shame. From experience take the shot that caught your attention, the zoom out and take a wider shot. If necessary you can add the missing bit in Photoshop!
