I miss Philly, such a unique city with so much character. There are great cityscapes to be had at night from Spring Garden bridge - right next to the art museum. Check the white balance to ensure the city is white, not yellow and enjoy (best when the trees are in full bloom and you can capture the summer humidity in the air)!
The idea is good, I like the statue, and the street leading up to the building. The dark buildings blend into the black sky too much, though. It's impossible to tell where the buildings stop and the sky begins. I think it would be better if it had been taken a little earlier in the evening, to make the sky bluer, and get more definition to the buildings.
