I am sure that this has been mentioned. If you read the challenge discription it explains the vanishing point definition. Aside from that the horizon is really skewed, and there is really no pop to the photo. I am also not able to really see what the main subject (other than fog) is supposed to be.
DNMC...after seeing complaints in the forum I'll elaborate. I see no converging lines. Is this whiterook? See the definition of Vanishing Point in the challenge. It's not fading into the fog. Maybe you considered the fence to be it, but it's far too far away and vague for me.
