The focus is supposedly on the crane and the sun. But after you mentioned it, the dark patches are starting to bother me too! Haha actually i like alot of sky to show the gradual change of colours. Maybe it's just me cause I like to have alot of sky, alot of sea or alot of grass... that sort of thing. So it's like the silouette and all are kept as stingy as possible. Yep, I can try a panoramic shot from the same spot the next time. Thanks
