Never too late for suggestions; if I am going to do something with them 
is another matter. ;-)

For those parts of the castle which show a definite shadow in the Sun 
(the tower) I used the displacement feature in Poseray. This is tricky 
business because you can easily overdo it and the effect becomes worse. 
So, the roof tiles and the stones in the wall were subtly displaced. The 
shadowy wall were not displaced though. Overall, I applied a proximity 
pattern to make the wall texture more interesting.

There are always more features to work upon in such a scene. I have a 
couple of items myself. However, before I get bored I prefer to stop now 
and maybe take up the work later (or never). Perfection is not my cup of 
tea. :-)
