Well I don't think there are pictures of the city skyline... there are so many different places that are built up around here, scattered around places with no tall buildings at all...
I have a couple different pictures I took myself... They're not very pulled-back... And one is bad quality because it was hazy and there's a reflection from the window... but still...

That's taken from a bridge between Arlington and DC... Looking towards Rosslyn... One of the most built-up places in Arlington...

That's a picture taken from one of the buildings in the first picture... Looking towards DC...
DC doesn't have much of a skyline because there's like... a building... height... limit... I could have found a better picture of DC's 'skyline' but I don't feel like trying...
