I think I saw these earlier posted in a gallery in some photo list. Alistair is right, you can try *not* centering the subject for a change and see how that works with you.
The photo of the church is quite striking and has good exposure. I like the deep blue of the sky amd the whiteness of the clouds and the church. It almost looks like you used a polarizing filiter on the lens. What did you do , or did you just get lucky? hehe
