looks good so far.
I do have a comment though...It seems to me that the fog is not any higher than the eaves of the houses and tree tops. This is because they stand out more. The hill to the left (I am making an assumption here though) is also enshrouded in the fog. I think the fog might be more believable if the hill was also clear of it, and the fog had a bit of texture or noise to give the appearance of thick or thinner patches throughout the map.
