The colors in this picture seem to be a little dull. Is that a ladder or a fence? I can't tell. The focus being on the girl kind of destracts from the fences challenge.
This photo did very little for me in terms of the challenge (fence?); as a portrait, it's too center focused and the model isn't sufficiently framed by the out-of-focus foreground for it to work.
Lovely smile, you've captured a nice portrait of her. One technical thing which would have helped this shot would have been to think about creative composition...in other words try not to put her head right in the middle of the shot. Also, the challenge is about fences and this isn't about a fence visually. Keep building your skills!
