Storm Clouds over the Castle

Took the dog a wander up to Blackford Hill after work tonight, the light was horrible with flat grey clouds starting to gather in preparation for the snow to come tonight no doubt. Wasn't too bad up on the hillside of you stayed away from the top and to the north side of the hill. With the light so crap it was always going to be a b&w shot tonight, so what better than Edinburgh Castle, taken with the Sigma 70-200mm f2.8.
