Gary - switch off that darn Gamma Correction and never use it again. It spoils your renders. We had discussed in the Steering Commette to either remove that option or give the user some control over it. As it is implemented, it is worse than nothing. Unfortunately, our rebelious but good meant advises weren't heeded.
Particularly the foliage of nearest tree at right looks like pulp. I first thought you used a lot of Ambience. Ambience is not outright evil (as gamma correction) but it must be used with utmost care.
Otherwise, I mean, you know, it's almost a typical Rebel. I like this artwork of yours very much. It has a merry touch. The water isn't that bad. Just increase the frequency and maybe half the bump value.
The lamp is very cool and I like how you put light into the house on the hill. It's not a dead place, people live here.
