Thanks for your comments. I did a re-edit like you suggested, I am using the free program Gimp, which is similar to photoshop. I made another mask I think thats what I did then adjusted the levels, so the sky was light and the church was dark, I then selected the dark areas and then went back to the main image, I did manage to get some better detail in the church, and it looked great. However I couldn't find a good enough way to decrease the brightness in that white cloud which I agree puts me off a bit. Then when I looked closely, there was a thin green line all around the church. I have no idea how to prevent that.
