Sorry Syl, that last one was a rush message, been plagued with conflicting mobiles texts all day.
What I meant was that it cools the stonework, makes it look much more real. Well, for this country that is. If the door/shutter was in Spain (doesn't look like Spanish carving mind) then the warmer sunlight might warm the colour of the stone, esp. earlier in the day.
Having it a little cooler makes it feel like cold stone and if this was on slide film and the sunlight was that warm I'd have used a blue 82A filter to cool it anyway.
Anyway, upshot of all this is - nice work. A plant wouldn't have gone amis in the frame, but can't put in what isn't there. OR - can you?
