The colors are wonderful, being overcast and all. But I think you could use more focus, and isolate the different parts of the scene. Do you have more shots of the place? Edit: Wow your gallery is quite something, amazing portfolio.
Lovely colours, but I don't understand how the trees on top of the hill can be so blurred, yet the sky again is so full of detail... did you originally have a different sky, maybe? Or a different background behind the hills all together?
