Technically Your picture is well done. The focus and exposure are right, You kept the camera or Your crop perfectly vertical, and the use of the fence in the foreground expands the depth of Your image, but I think if You cought some kids playing soccer on this field the photo would be more alive.
Thanks a lot Mirek, when I took that picture I was more looking for emptiness rather then liveness. Anyway it would be interesting to see the different result with some kids playing there. If you have time please have a look to the rest of the series "Carbonia". It would be nice to have your feedback. Cheers, Anna
