Does not not do too much for me neither
branch in the foreground :er: , and washed out colour , I may suggest you to crop the white part of the building (to keep only soft colours) and remove with PShop the branch
The blue inside the cross, its yellowish border and the blue of the sky make a nice image. The noise is distracting (but there's always NeatImage for that), and so are the twigs... and the white corner.
But it is not yet one to be thrown away. You can still do something with it. And if it is testing all your conversion skills, or trying out anything that might help along with converting it (though I do appreciate the two blue-s).
