hmmm.. I wonder what that shot would look like in colour...If it wasn't for the title I think I wouldn't have guessed that it is a silo...
As it is the subject of your picture I think it would be good for it to stand out a bit more...in my opinion, with the really light background the also very light-coloured silo doesn't attract the eye enough... maybe a closer view or a different composition (with the silo a bit more to the left f.ex.) would do the trick aswell...
but thats only my opinion I think this picture has great potential anyway
In the original of it (which is quite large), the Silo seems to stand out more. I had a color photograph of it and the Silo was more to the left but it came out a bit fuzzy. I also have one in color where the silo is right in the center of the picture but it looks far away
