Thanks for the feedback.
Olli, I tend to go for the High Structure look in SFX as it gives me the gritty look I like, I know all images are a case of personal preference and each person will have a different opinion.
I also find that with trees against sky, the High Structure gives me more of a 3 dimensional feel to it and makes the trees stand out more from the dramatic sky behind - I also find that the sensor on the X100 contributes a lot to this effect.
