I really like the tree here, everything is very well exposed. It would be really great to see the roof and pole the the left removed some how (either a big cloning job or waiting until the sunset occurs at a slightly different angle). However, I really like this one.
You have exposed the sun nicely here and created a good silhouette with the branches but for me this is a little too busy. Just isolating the branches and losing the building would work better in my opinion :o)
The color and upsweep of the branches make this an uplifting photo for me - I think of dawn. The image would be better without the pole and the large black object on the right.
A tighter crop would have worked wonders I think. the sun & tree siloulette is stunning, but the roof(?) and lampost/aerial add nothing to the photo. Good spotting though!
