When TPF automatically resizes photos, make sure you click on the bar above to get the original size. The TPF-resizing leaves photos quite pixellated and ugly. You have to look at them in their original size.
I agree about the dark cloud.
Though on the other hand, I like that bit of "sinister aspect" of it, of something dark creeping in from the side --- though that thought does not go quite so well with your tone-mapping :scratch:
I really like the photo, but I agree that the cloud on the right should go. It looks like someone's got a woodpile burning out of the frame or something.
