Well. There is a lot IMO that can be improved upon here. I think a portrait crop would work great here. As it is now the trees are in the way and the statue takes my attention away from the capital building. The focus sems a little off but you could probably fix that witha slight sharpen. The color in the sky is a nice bright blue that makes the building stand out. I would say with the time that you took it that a tripod and a longer shutter speed would help you. The lighting on the capital shows up good but everything else is very dark. Also the building looks tilted and that probably hurt you more than anything on your score.
instead of landscape, this should have been shot in portrait. and closer to the main focus of this image, which I assume is the dome. The bottom building distracts, and you can not clearly see the peek of the dome.
